Best spot east coast USA to learn prone in late winter

It’s gotten into my head that if I could go to a place with a good prone setup, where there’s a good chance of decent conditions, and go out for several or more hours/day for like 3 days I’d break a plateau I’m at. Being winter I’m not likely to progress and it’s not as fun TRYING to foil when it’s damn cold. So where can I escape to? Thinking late March which is actually spring but that’s when I might be able to swing it.
