Soapstone has a little of everything, the aera is mostly glacial till. Its not "rutted out" it is just very rocky. I've been riding there for years and the trails have changed very little. They do log sections of the forest from time to time, and some trails have been lost. But new ones have been built.
I have ridden Cockaponset a few times.
"When the spirits are low, when the day appears dark, when work becomes monotonous, when hope hardly seems worth having, just mount a bicycle and go out for a spin down the road, without thought on anything but the ride you are taking." - Arthur Conan Doyle
