There is a trampoline-place-type deal in Glastonbury, CT that occasionally has open gyms. For the most part they are a gymnastics-only business, but recently my friends and I have turned them on to the idea of skiers practicing there. When I went in and asked about open gyms, the first thing the chick asked me (she was hott, too) was whether I was a skier. The open gyms cost $10 for 2 hours, and the gym consists of trampolines and foam-pits. I tell you this secondhand; I heard it first from BKCountrySkrMO2 (yes you hate him) but anyways it seems dope. Its located near Smith Middle School in Glastonbury...hopefully I'll be able to provide phone number, address, etc later.
Just a friendly heads up :)
