I did that 2 years ago. It's a challenge, since you climb a couple of mountains in the century, but shorter versions don't have as many climbs. If you want to do the full century, you'll at least have to ride a lot of hills by the time of the century. You do ride by civil war sites, South Mountain, Antietam, and Gettysburg. Gettysburg is toward the end of the route, so you mayl be tired and stil have to deal with cars and pedestrians on the roads there. The rest stops are good, and there is bluegrass and great ice cream at the end. Parking is on a grass field, so parking your car can be a rough ride. By the way, thanks. Now I'm eager to do it again this year.
