I will not leave my bike anywhere unattended. I have been out touring and stop for snack or something and take my bike in with me. If I am asked to leave my bike outside, I find another place to spend my money. Locks don’t work , at all! In California anything valued at $950 or less is a misdemeanor and you would be hard pressed to get an officer to even take a report. They will write a ticket if they catch the thief in the act, but that’s it just a ticket. The bike thieves know this and bikes are being ridden around with rattle can paint jobs , handlebars and all , mostly the homeless with backpacks and or trailers in tow. I was trying to get around one on a bike lane when I noticed a pair of bolt cutters hanging out of his trailer. I don’t use my bike for shopping or anything anymore , I just ride it and put it away.
