Hilly metric century from Frederick, MD. These are some of my favorite roads and hills. Be especially careful on the descent of Highland School road, remembering that there can be deer, oncoming cars, and occasional gravel on the pavement. There are stores at mile 18.6 (in Wolfsville) and mile 45 (a Sheetz in Thurmont just east of route 15) (thanks to B. Randolph!)by huntley
