I also live in Florida... down in Miami.
Being a boarder and living down here is extremely inconvenient. Anywhere we travel will result in loosing a couple of days... one getting there and one getting back.
Unfortunately the closest resorts we have available are in NC, but the snow quality is terrible.
The only thing that compares to Colorado powder on the east coast is Vermont.
I recommend a resort called JAY PEAK.
You will love it!
The snow quality is superb, the resort is top and the people are really cool.
Believe it or not, travel time by air is not that much longer than NC...
Anyways, good luck boarding anywhere adventure takes you!
