Just playing around, came up with this. It starts in Kingston, R.I.(Amtrak access), goes 126 miles to Danbury (MTA access). All 2 lane roads as far as I can tell plus 2 sections of bike paths. I would check the whole thing thru Google Maps before using it, I did not do that. I used the Cycling routing of RWGPS, which normally re-routes off roads that might be inappropriate to bikes. A stopping point might be Middletown, CT., which might then involve detours to get to a hotel, restaurant, etc...
