You could PM or email Preston Curtis, the MA Chapter President, to ask him what he knows or if he's near there. Here's his contact info: Barefoot Runner Go ahead and tell him you heard of him through me, if you want.
I checked MapMyRun, which I have an account with, but don't usually bother to pay any attention to for my own home stuff. But I checked on runs near where I'm going ot stay and was rewarded with a long list of options. The best looking routes were all posted by the same guy who used his own name to post. I looked him up in the White Pages and called him. In the end I got detailed surface descriptions and consider myself ready to run when I get there and I'm very pleased.
