Replying to Places to tramp in boston/northeaster students?

Hey New Englanders.

I moved to boston this year to attend school at the boston conservatory and I have to questions.

1. are there any good gyms in the city that any of you could recommend me that have open tramp sessions?

2. Any of you guys go to northeastern? We eat at their cafeteria and stuff and was wondering if there is any freeski community over there.

Thanks.
