Ended up going to South Branch and rode the Huron Trail to Sand Lake. It was a nice ride. Started out fairly tight and hard packed then turned to loose sand with long straight aways and big sweeping corners.
Loaded up and went to Rose City, unloaded west of town and rode the Ambrosea (??) trail north towards Luzerne. That trail was tight single track and was very fun. Put on about 100 miles in one day.
