Dude... this is going to be bananas. The entire state of Vermont gets inundated during President's Weekend/Week, but it will be acute this season given the snowpack, region wide like 100% open, well-advertised snowstorm, etc.
Exit 10 is the epicenter, go north to Stowe, or south to the Mad River Valley/MRG/Sugarbush. Locally, the whole Stowe area is going to be bonkers... the the village in the evening after skiing, the Mountain Road during the morning and afternoon rush hours, the mountain in the powder portal, high winds possible Sunday and Monday.
Even so, I'm always happy the vacationers get to experience a snowy/wintry trip. The weather and conditions go to shit for so many holiday vacation periods, the vibe is so much more upbeat when conditions are great and folks are into that winter storm excitement... despite the gong show occurring .
The high visitation plus the roads being rough will lead to some super frustrating driving, traffic, even temporary road closures by PD if vehicles can't navigate Harlow Hill... I try to go into it with an open mind and enjoy the chaos.
