nice thread, I'm not from nor live in DC but this is a very interesting to me. I'm an avid photographer and had just recently started commuting by bike in NYC.
I envy those awesome bike lanes you guys have. The dept. of transportation of NYC has been going through the similar trend as those in DC. Re-structuring streets and develop greenways and bike lanes. But NYC has a long way to go still.
great thread again, enjoying going through the previous 15 pages.
