Lived in Rochester as a kid.
Route 100 is fun in sections, there used to be a race, the 100, 200, 300.
Warren to Rochester Vt on 100. Picnic near texas falls, check out the dairy near rochester and the bike shop/ clinic across from the grocery store (old ski lodge i grew up in) ride over Mt. Horrid pass (not kidding) to Ruteland. Camp at the lake (just watch your descent it's STEEP.)
Lots of good memories, the perfect state to cycle in.
have fun.
