I'd like to make a trip to Circle and pull my atvs up that way too. Any good trails to ride? I have a 6x6 sportsman & 6x6 Ranger. Looks like the Quartz Creek trail is closed to vehicles over 1500lbs, sxs, etc.. (Gotta love the feds.) Any other trails worth riding up there? Plan on riding the Chena Rec Area too.
