The DOT has recently unveiled a Google map interface showing the locations of 5,968 bike racks (out of approximately 6,100) that have been installed throughout the city since 1996. As you can see from the map, there are CityRacks all over, which doesn't explain why it's such a pain in neck finding a spot to lock your bike anywhere near Caracas on First Avenue. The map's certainly a nice gesture, but will cyclists will actually consult it? There's almost always a signpost or something you can lock your bike to within a block of your destination, and seeing a bike rack on a map doesn't mean it will be unoccupied when you get there. At any rate, the DOT will update the map as new racks are installed, and there's a form on the website that lets you request a CityRack for your block.
