If the trail you went down was really bumpy!, I believe you are talking about an area called the Batson Tracks or Hurd Creek Estates/Shacks depending on which house you are checking out. Actually a pretty cool area with good access and a lower price point than the CR 8 area. The plowed road you came to is CR 848, off of CR 841. It would be good to have another sledder represented in that area but you wont have many friends if you move in. Someone up there likes to put nasty notes on your sled or truck written on Grand County Sheriff business cards. They picked up the cards somewhere, then pretending the deputy, they write a note saying that Sled access is illegal or something else defamatory against sledders. Access is not illegal if parking on a county road and not blocking traffic or home owner access which I confirmed with the Sheriff Deputy. He also wasn't happy about someone using his business cards.
Hope that helps. There are a couple areas like this in that area, but this is the only one with dedicated national forest access, which might change in the coming years depending who buys the private ground further up Hurd Creek Road. There is a pretty good short sale listing right now up Hamilton Creek (Home/8 acres/$250k) which is right next this area.
