I'd like to second what Jim said about the Eire Canal, both ends. A great trip, wherever you goeth.
I spent 2 weeks in Waterford, waiting for the water to go down and for Judy who was waiting for a grandchild, back in LA. It's a great town, there's a great restaurant for breakfast, etc and there's an original section of the Eire Canal leading to Albany. Also, if you've missed Rome, they have a wonderful Eire Canal museum, which was going broke in 2002. Well worth a visit to understand what the first canal was like.
Don't forget Troy, home of Renessalier Polytechnic, which I used to visit when they were doing NASA studies for a Mars Roving Vehicle, back in the 70's and I was at JPL. Worked out well.
Also, you can head up through Lake Champlain from Waterford. Or join the Canadians headed down the Hudson. While they lower their mast somewhere on the way down, the C-Dories are a great river boat.We moored off New York for a couple of days, right near Central Park, on our way up to the Eire Canal.
Note that the 3 ea comments you have come from Texas, Colorado and California. Probably takes some distance to appreciate the Eire Canal.
Here's a couple of pics of the west end. First, lined up at the Waterford dock waiting for the water to drop, in June. Our Journey is the first in line showing how long it took for that kid to be born.
Next is s hot of downtown Waterford, a very nice place.
And finally (hold the applause,) a shot of the old canal, leading up from Albany. There's an old lock in the background.
Truly a great trip, Boris
