I like to post my questions in the subject field. Now that I have a pannier a good saddle and lights on the bike...what do you all do when your for example in the grocery store? Do you haul your pannier and seatpost with you? Do you feel comfortable leaving your bike locked up outside? Any fear someone will swipe your stuff? I wish I could leave my bike un-locked and not have to worry about bike theft. I'll never understand the mentality of a thief.
