Look up bug out bags on youtube. They have some interesting ideas.

I have to travel a lot too for work, though not usually in remote areas. Bringing a bug out bag may not always be possible. I always bring my little macgiver bag that has a bit of everything in it, the size of a lady's purse. It fits in a suitcase and though not comprehensive, is better than nothing. Always have warm clothes with you.

Lastly, bring cash! You should have enough cash on you to buy a plane ticket back home (or charter a small aircraft) if needs be. A credit card is nice, but cash will still work if phone lines are down!

Look up "get home bag". Sounds like you've been prepping, but now you're all over the place, destabilized. You need a bag that will get you home by foot.

This is gonna be difficult with the weather. Honestly in some parts of Canada, if you don't have a sleeping bag equipped for -20 at least, and even a pad to go with it, you're @#$%#. These are probably your most important man. Some people might disagree with me.

I have a get-home bag. Haha but it's a joke because I work 20 minutes from home(and my bug out kit). Here's a list of some of my "get home bag" items, if you can call it that.

-heavy duty tie downs
-bicycle frame bag that fits in my backpack as a tool bag(every tool I would need to build a bike from scratch, including pump)
-spare batteries
-leather gloves
-winter face mask
-1 pair of wool socks
-long johns
-granola bars, sesame snaps
-1 litre water bottle
-2 flashlights

On my EDC key chain I carry...
-Gerber mini-swagger pocket knife
-a seatbelt cutter/knife sharpener/bottle opener
-LED maglite

Other options I considered were firesteel 2.0(with the striker/whistle) and if I had the room would plan to add a small needle noes multitool, possibly even a small capsule(the size of a chapstick) packed with cotton balls saturated with petroleum jelly.

I don't think I particularly need firestarters. I live in a huge city, maybe I do, I don't know. It's just that theirs lighters everywhere, and I could literally jog home in fifteen minutes. But for YOU?? Yeah I'd pack em, flying over the wilderness and such. Obviously you can't take blades on a flight, but maybe this will give you some perspective into what constitutes a get home kit, or bag.

Hopefully this helps you with your decisions.

EDIT- I also have an assault backpack, which means there is MOLLE compatible stitching all over it. This means I could easily use the tie downs to strap extra stuff to it, this is important for you especially.

I also have considered picking up an extendable baton and pepper spray, possibly even bolt cutters and glass breaker but those items could land you in serious trouble if you're caught. Pry bar would work too, for me at least being in an urban setting.

You should look into stuff that'll let you know if going home is worth it. Radios, solar and crank powered chargers and such.

Also, and I know no one mentions this on this site for some reason, but are you in shape??? Would you be able to walk across BC?

Since you don't have access to gyms because you're commuting I'd look up a book like this...

http://www.rosstraining.com/nevergymless.html

Bought this book back in 2007 and I still use it and lend it out, with the info in this book you could train to be in top condition and stay that way for the rest of your life with nothing but your body weight.

I feel your pain. I spent several years making flights that required me to have appropriate office and evening attire, plus stuff suitable for site inspections. Talk about maxing the bag limits fast; at least guys' shoes will multipurpose more.

I used to have the little Altoid and CD zipper case sized EDC kits, and I'd stick them with small repair kits for eyeglasses and electronics so they didn't raise eyebrows. Once airline restrictions tightened, it got harder. I carried some cash, but regularly carried the $50 and $100 USD "cards" with gold flakes and junk silver. I purchased an umbrella that was built for self-defense - pricey, but you can whale on a tree or heavy bag with it without a dent or rip; make sure not to get the ones with blades for airline travel if you go that route, or that you can pack it and it's legal wherever you're going, both the final destination AND layovers where bags will change planes.

I also carried good rain gear because it can vastly improve your weather resilience with very little space, trash bags to accomplish the same for my feet, and thermals. I kept them wrapped around duct tape on a PVC rod that held my coins and a pair of socks that held my cash, a pill bottle with matches and a few other little things, with bungee cords keeping it tight. That 8x10" bundle could get me a fair distance on its own and could be reconfigured to fit in an attache case or messenger bag with my laptop and a steel water bottle and some granola bars or sit quietly at the bottom of a light backpack for a carry-on. I always had good shoes/boots with me, even if I wasn't going to be hitting any sites or touring.

I stopped carrying emergency ration bars and went with granola and peanut brittle candy bars. They just attracted less attention. I also carried a small first aid kit.

Going home was always worth it to me. So before I left, I printed maps of the areas I'd be in right off Google so I could mark areas to avoid, areas with resources, and landmarks and a few street names and addresses.

Lifestraws are small and lightweight, and would be in my bags if I were still traveling.

KenVii2,

Another option if you keep on returning to the same locations would be to stash some stuff at those venues. Extra clothes, food, etc. it can be as simple as leaving a Rubbermaid bin at a coworker's place, to renting a small storage space, to burying everything somewhere in a cache.
