I locked my bike up at the bike rack on the south side of Caltrain at 4th/King. I walked away for about 40 minutes and came back to find my bike gone. After asking if anyone had seen anything, I realized that the bolts that held one side of the bike rack to the concrete had been removed. You could pick up one side of the rack and slide the locks off of it before putting the bike rack back down, making it hard to see it was broken.
