If you're so inclined and are of the Woodstock generation, you can visit the Bethel Woods Center for the Arts just east of Bethel, NY. This is the site of the famous Woodstock Music & Arts Festival of 1969. There is a Woodstock Museum at this site that is very interesting.
If you take I-84 through PA and into NY you would take Hwy 17 at Middletown, NY northwesterly to Monticello, NY and then 178 west to the western edge of Bethel.
You can go a bit further north and catch I-88 and head on up toward Maine.
