You may want to check out the Western Maryland Trail. It's 22 miles long, straight shot, flat and very little in the way of other bike riders, walkers, etc.. Just keep an eye out for deer and snakes. It's about an hour from where you are but worth the trip. Take 270 north to 70 west. Exit 12 off 70, make left trail head/parking is about a mile down the road on right. Clean potta potties on each end of the trail and it goes through the town of Hancock at mile 10 for places to get something to eat.
