I know Augusta is a long drive for most of you, but Bond Brook is such a killer place. The opportunities are getting better and better too -- You can run from there to the Rail Trail, go several miles, end up in Vaughn's Woods in Hallowell (several more miles, and you can add in a speed workout at the Hall Dale track, which connects by a short side path), back to the Rail Trail, to Gardiner (4-5 more miles?) back to Augusta, to the UMA trails (via Bond Brook). Or cross the river right near the Rail Trail, where I believe there is a trail that links to the Arboretum, and all its trails.
It's sort of amazing to me that Augusta, a place everyone loves to hate, has this gem of a trail system, right smack in the middle of it. I have no idea how many miles this-all is but it's a lot, and my point is, it's worth the drive if you need some very hilly variety.
Okay, enough raving for the moment. Feel free to give a shout if you want to come down this way! The trails don't have good signs yet and it can be really confusing in there; I'd be glad to attempt to help show anyone around.
