I feel ya, man... really, I do.
But this happened in front of a huge fitness club during prime time hours, right in front of the taxi stand (which is 2 steps away from the bike stand). I will photograph the area and post it next week, if I remember. Plus, the bike stand is literally in front of the windows of the management- their wall that faces the bike racks are literally less than 5 feet from the window, and the whole wall for the management office, which extends for about a quarter block, is all glass. I'm thinking- "in front of all this, how could someone snap the chain this quickly?". It seems like there's something odd going on here, or I am just being naive.
I'm still perplexed.
