hi, i'll be in Manhattan for a few weeks starting this weekend. i'm planning on bringing my Bike Friday (or just finding a half decent beater in the city?) and i'm excited to ride around manhattan but also to do some longer, less trafficked rides outside the city. can anyone offer any recommendations for some longer (day trip to overnights) routes? and perhaps a way to get there, ie. train connections etc.

i'm also thinking of a short tour up the coast or the adirondack loop using the adventure cycling maps.

oh, and is there a generally agreed upon best lock(s) to buy?

thanks!
