Places to Ride

I live near Annapolis and ride in Rosearyville Park most of the time. So far its the only place that I know of that can accomidate my SS CX. Ive ridden in Lock Raven but it seems to be made for Moutain Bikes than CX. Just difficult I cant keep my momentum up to climb those hills. Other places Ive been seem to be to difficult to traverse or to easy. I looking for a trail similar to Rosearyville. And if any of you have groups that meet near my area please dont hesitate to contact me.  Thanks lukasrolf@yahoo.com
