This forest has a quiet little 2.5 mile loop trail through some beautiful woods (on Ushers Road in Clifton Park cross roads are English Road and Rt 9, there is a little parking lot). Lots of old trees and birds singing on a brisk afternoon. There were a few bridges to cross over streams.
A path diverges from the loop and connects to the Zim Smith trail, which we had never taken before. Along the connector path was a rusted over car coated with snow. 
The Zim Smith trail goes on for some length and is very flat. We were walking beside many backyards and signs that say ‘quiet’ in numerous ways, I guess these people want their privacy and I can’t blame them. 
We decided to just walk a bit and then turn back and complete our loop at Ushers, a much more serene place to be.
