Here's a nice 10 mile loop around Cortland and then over to Mt Airy for a little hill climbing. One of the hills is really tough, but coming back on the other side is nice. Some great
curvy hills. Edit: Here's another 10 miler that avoids the horrible hill and runs past Croton Reservoir instead. Turns out the name of that
hill (I am not lying) is Torment Hill.
