you can go, you have to sign an a form attesting to 14 days of quarantine before you travel to VT, or 7 days quarantine and a negative covid test, something along those lines. I have basically been quarantined since late March, so it wasn't much of an issue for me. The only place I've been indoors is Stowe in August. Any place you stay, will have the info for you. Just make sure lift tix are available where you want to go. I like whiteface a lot, but my guess is the skiing in vermont is much better right now. the whole state got over 2-1/2 feet last week. some places got over 3 feet. That's a lot more than whiteface.
make sure you sure that attestation form, somebody in front of me at Sugarbush couldn't get through the lift because of it and had to walk all the way back to the ticket office.
