I agree that Roscoe NY is a quaint very small town, that I really like. There are several campgrounds there. It's a fly fishing haven right off rte 17, which is a VERY scenic highway that follows a river. But 17 is being turned into an interstate, you might run into construction.
The high ground above the finger lakes offer beautiful views of the lakes, especially Lake Cayuga, with it's many wine vineyards.
