Is Clinton a tourist destination?

I would say not really. I figure its main draw is probably the winery, Clinton Vineyards (though there may be others in the town of which I'm unaware, or I'm just unaware that they're technically in Clinton). You'll always get out-of-towners visiting the wineries up here, regardless of where in Dutchess they are, but aside from that, there doesn't seem to be much of anything else to see in this town. Neighboring Hyde Park gets a lot more tourism with the Roosevelt and Vanderbilt estates.
