Yep, riding in NYC is a lot of fun. You wouldn't think so, but there are lots of places to go that you won't have to deal with NYC traffic. The West Side Greenway, Central Park, Prospect Park, the bridges, Brooklyn, even the Bronx. Riverside Drive is more bikes than cars on a nice weekend day.

I'm back in NYC now from Seattle and I'm looking forward to riding here again. Seattle was really nice, but riding NYC is more fun. OTOH, I had a lot of fun off the bike in Seattle too, NYC is just home and work.
