If you go by water you have to plan on staying somewhere else - the Waterford docks will be full. Take a look at the July article in Boating on the Hudson towards the back of the magazine, it lists Southern Saratoga area marinas and nearby services. A challenge might be arranging local transportation unless you bring bicycles, but if you really want to visit (and I hope you do!) let me know and I can work on something for you. When I'm not boating in the Hudson Valley I'm the local Chamber of Commerce president in southern Saratoga County, and I'll be at the Roundup with my team that weekend.
