yeah, sounds like the kinda trip i'm thinking. the century on the first day is the bulk of the riding, but it's all flat out long island. then two chill days with some nice relaxing on block island and hanging in providence and boston. the route i'm thinking skips connecticut.
i'm confused though why you Bang Boston folks would have used a larger cog on your freewheel side than on the fixed. seems like you'd go with more gear inches for freewheel. maybe not though...
as far as packing i'm thinking we can pool a tool kit. the bang boston site has a good general list of stuff to bring, as do most cycling books.
crap, i'm late to meet someone... later!
