Sounds like a nice ride. I like the Catskills but a bit too crowded. Of course not by Long Island standards. If you do get the chance you should take a tour of the Adirondacks, after that head over to Lake Champlain then up to Montreal. After Montreal come back down through Vermont, MA, CT and over to LI. You won't regret it if you have time. Of course if you really have time, after Montreal swing east while staying in Canada, go over to and around the Gaspe pennisula, Nova Scotia and then Prince Edward Island. Then back through Maine, down etc. I've been lucky enough to make that trip twice. Memory of a life time.
