Mason, try St. John's Ambulance and see if they offer the wilderness course in your area. You can try talking to local stores/outfitters for camping and hiking and see if they can direct you at more extensive first aid courses. Another place to look for information might be anywhere that rents boats/canoes/kayaks?
