I left it at the Palo Alto Caltrain station locked to a tree and when I came back the lock was cut open.
The weird part is my bike was still there seemingly untouched. I guess the would be thief got interrupted.
Note to the reader, this is a different bike then the one that was almost stolen in waterloo, but it's of the same "quality". I guess the fact that people are "almost stealing" rather then full out stealing my bike is a good thing.
