Good skiing closish to Boston or New York for day trip.

I asked this question last year and ended up heading to Mount Snow, where I
had a good time despite the bitter cold.

so same question again, Who has good conditions within a similiar drive
time as Mount Snow? Last year it took me a touch under 5 hours with one
stop for coffee. I will only get one days skiing in.

I could fly into either Boston or New York, but need to head back to
Trumbull, CT on the evening after I ski...so would want to be within say a
4 or 5 hour drive of there.

I mostly ski Europe, off-piste and difficult runs, so am after
anything good and reasonably challenging

thanks in advance,

Greg
