re: Med Kits

I'm enjoying this thread. I hate to say it but I've been thinking about getting or putting together a small med kit to keep in my hunting pack in case of emergencies, but never acted on it. Not sure what I would need or if a tourniquet is a necessity, but reading through these posts seems like I should at least consider one. I normally bowhunt but sometimes gun hunt, and am anywhere from 1/2 mile to 1.5 miles away from the road on public land in most cases. I'm sure things can go awry in a hurry unfortunately and I need to quit waiting and just get one. Any recommendations for what I'm looking for and if I should get a tourniquet as well?
