There are things I could lock it to. At the grocery store there are some poles and stuff but just seems like a hastle because they are so thick. It's also akward to try and lock my front wheel to it also (after removing it). Also the ulock dosn't fit around these poles.
At my school all the light poles around campus have thick concrete bases which scratch the paint on my bike, so I prefer not to use them.
I think bike racks are much easier to use and bicycle friendly. Also when a bunch of bikes are locked up together it gives me more of a sense of comfort about leaving my bikes there longer, don't know why though. Guess it shouldn't matter.
