Pros: Value, proximity
If you work and live in Boston, like I do, and you want to get some turns without having to drive 2+ hours then Pats Peak is your destination. You can make Pats Peak in a little over an hour on most days from Beantown and it has some steeps (albeit short in length) for you to fine tune your edge before you hit, say killington or head out west. I would forgo going to Wachusett or any other area in southern nh as you will most assuredly hit crowds. Pats Peak is a nice little gem of a mountain close to boston.
