Questions: For you guys with the panniers, when/if you have to go into a store do you leave your panniers on the bike or do you take it with you? If you do take it are there any that are easily carried around with you? I'm asking this because this is what's stopped me from considering panniers before and why I've gone the backpack route. I usually stop at high foot traffic areas like the malls, groceries and I feel uncomfortable leaving anything on the bike.
