This past summer found us in Pennsyl-delphia and New York (South Central, Syracuse and Southeast Corner...) we stayed in the state park system mostly...
I would not recommend Syracuse (Green Lakes...) far too over used... But...
3X on Letchworth and the Grand Canyon of the east... Very nice!!! (even follow that down to Mansfield and Kettle Creek in PA (or start there...) Highly recommended... (but use Rt 13 because I-81 was a mess...
Taking the rout through Ithica and Elmira was beautiful!!!
And, of course, back tracking down Rt 17 to Middletown and Bear Mountain... Again... Very nice and highly recommended...
