I would suggest you also check out these roads, which include the 520, Ahmic Lake Rd, the Bunny Trail, McDougall & Hurdville Roads.: Burk's Falls to Orrville
Also on the east side of Huntsville are a bunch of really fun roads: Huntsville to 144 ON-60
And if you are good to venture as far away as Haliburton, then between Huntsville and Haliburton are a bunch of great roads, a couple of which are out 'n backs, because they either turn into gravel or become a dead end: Huntsville to Haliburton
You're the man, thanks so much. I wish I had any directional sense.
