A hair pick and Leatherman tool with pliers are absolutely as essential as toilet paper. The pick is used to flick cholla burrs off myself and the French Brittany and the leatherman pliers are used to get any left over spines out of me and the dog. I just find it hard to walk with my hunting pants nailed to my shin bone by cholla cactus spines. Hunters from areas without cholla just haven't seen anything as nasty.
