Well, I answered my own question. I parked at the post office at the bottom of Huntswood (Greenwood).
The power lines apparently go from Miller Road to Route 4. Just past Miller Road there's a small gulley with a bridge that's gone. On the other side of Route 4 (by Friendly's) we couldn't figure out how to get past the guard rail. The route is about 2 miles end to end, so unless you like going back and forth (and back and forth and back and forth) it's pretty lame. If we could figure out a way to get past Friendly's there would probably be another 10 miles to go.
Regardless, we went back and forth about 3 times and it was very cool since it was only the second time we were able to get out this year. Plus, even though it was only two miles, we got to break trail through the powder which is always fun.
