I started riding in Superior and went up Queen Creek the back way to Clayton Tunnel
And some highway to get to Oat Flat. I mostly perused each of the possible avenues; according to aerial shots, both seemed viable. Here are some shots from the rest of that trip from the phone.
Side ideas for route:
-Apache Leap (3-mile RT hike)
-Roger's Canyon Trail (cliff dwellings, 4-mile RT hike)
-Devil's Canyon View Point (1/2 RT ride)
-Silver King Office (probably would be just an out-in-back from Superior)
