Watch your pack at all times, it's your home. If you have to go for water & there is nobody you trust to look over it, take it with you. In town at stores ask at service desk if you can stash it someplace or put it under your cart on rack there. At Wally worlds ask the greeter. Most store will let you. If not ask for alternatives & hopefully you have friends that can do shifts pack watching while you shop. What most local cops don't realize is theft of a pack can often be consider grand theft, $1,000 + When you figure everything in it it adds up! What it will mean to you on the trail is, end of your hike & transportation home or getting all new gear & possible days at hotel/transport to outfitter.
