"The Tugboat Roundup is September 5-7 at Waterford, NY. It's one of the largest tugboat gatherings in the Northeast. This year they are expecting over 30 tugs. What may be interesting to your readers is a lot of the tugs will be making their way up the Hudson the week of Sept. 1st. This is really a great event with historic boats, music, food and fireworks on the Erie Canal.
Also, check out some great shots of tug parade."
Thanks to Mike for this tip. I watched the promotional video above and in addition to tugboats (which you can ride) and fireworks, there is apparently a "line-throwing" contest. Presumably, this is the maritime equivalent of hitting the bell with a mallet at the state fair.
