There are trails on the powerlines. I don't ride them because of big rocks under fluffy snow.
I ride a small trail that I cut out in the woods behind my house. I pull the kids on sleds through there too. Their sleds with two kids aboard are my groomer.
I rode in the yard today, the plow made some big mounds in the driveway that double as jumps. There were a few trees down on the trails, but once cleared it was some fun riding.
did 20 miles on brookline trails yesterday. Nice snow, a little too fluffy. loose in the corners, little bumpy (could feel the rocks and stumps), first tracks most of the time, found some new trails to play on. sled ran great.
