Since I've moved to New York (about a week ago now) I've found that getting around is really easy. These folks have trains and buses going every which way and you can get an unlimited subway pass for $21 a week. That's so cheap compared to DC, were you can't even buy a weekly pass. If you could buy one, it would cost something like $40 or $50, based on the partial day unlimited pass. But even with all of these affordable transit options, I still prefer my bike.
I found this puppy on eBay a few months ago. There is a fellow on there from Southern California who gets some good old-school bike and sells them pretty cheap. His username is cino59 if you're in the market. The only trouble I'm having here is getting over the Queensboro Bridge. The chainring on the front is a little too big for me (50) and that bridge is quite a climb - especially going from Manhattan to Queens. I think I need something smaller.
