If I’d be vacationing in a valley between two 2500ft mountains, I think I would start with close call, and banks of generic frequencies like FRS, GMRS, Marine VHF (there are a few lakes over there), MURS, the hundreds of national railway frequencies, and generic aviation freqs.
If you still have time to prepare, add to these generics, any of the plentiful freqs listed here in the database section for Vermont (the mountains around that place may host some good wide area repeaters for services you’ll find in the database here).
Don’t forget to check the Scan New England website too.(
