For you veterans tourers out there.
What's that one item most likely to make you turn around to retrieve? I'm guessing your all pretty good improvisers, but there must be something you can't (or just rather not) live without. Maybe it's that spork/can opener/pasta strainer combo tool. Or the compass your granddad used in WWII. iPod? Lucky gloves? Lipstick? Help the newbs out with that one secret item that makes your tours easier or happier or just luckier.
I've been obsessing over packing lists for my first tour and figure with your help I'll end up with the kitchen sink and lipstick .
