One event in that neck of the woods is the annual Tug Boat Roundup in Waterford NY, which is at the confluence of the Hudson River and the Erie and Champlain Canals. It is usually the first weekend after labor day, but their website has it as "to be announced".
http://www.tugboatroundup.com/ It's a townwide celebration of the canals and tugboats, with tours of commercial and privately owned tugs. I'm sure I'm not alone as being a fan of tugs, every boy's fantasy boat.
There are free ty-ups for early birds, and a free ramp and parking for several rigs. Just 2 or 3 miles North of Waterford, at lock 1 on the Champlain, is another good ramp and parking, and another couple miles to Mechanicville, a good town wall with free power and water.
I can enthusiastically recomend any of the canal system to anyone who hasn't been there. The canals are beautifully maintained,(they spend $60 mil a year to maintain, and take in $2 mil a year in fees, the rest comes from the Thruway Authority), wonderfully under-utilized, and very inexpensive. Most of the canal-side towns are economically depressed, so you just need to bring your own entertainment.
We cruised the area on a pontoon boat on a cruise in 2001, just days before the world changed. Coming home from a great vacation on the morning that the twin towers fell made for quite a mood change.
