The Walmart here in San Jose is located near an unsafe neighborhood. The parking lot is full of unsavory characters who test the handles of car doors to try to steal things. The employees are generally friendly, if a little dim. My problem is that there is no way I would lock my bike up outside, even in broad daylight. There are too many potential thieves in that parking lot. I'd come back to a bike missing everything which wasn't locked down.

I only go to Walmart for range ammo these days, so I just drive over before driving to the range.
