NYS operates a website http://www.canals.ny.gov/index.shtml
for all things Erie Canal. If you have never been on the NYS canal system it is worth the trip. Very very relaxing and slow - not everyone's cup of tea but Pam and I find it just lovely. Lots of free or really inexpensive places to tie up to and explore. BTW the latest info shows the entire canal system open as of May 1 2012.
