I am a Type A in a lot of things, but not with outdoor adventures. When DH and I do local hikes, I always have certain things in my waist pack; like my headlamp (it's small) and extra nutrition, Nuun, and first aid stuff.
One time I was on a CRW metric century. About half way through, 2 guys stopped short in front of us, because they thought a driveway was the turn . DH got around them, I barely did, but the woman behind me, who had been riding with us hit me and crashed. Everyone else left and there were no support people around. People always make fun of me, because I pack so much stuff in my seat bag, but while DH worked on fixing her bike, I was able to clean her road rash, put on antibiotic ointment, and give her an Advil.
