So the trek for me could be 185th to Germantown and Old Corn Pass to Skyline... and then down McNamee or Newberry. Rinse, repeat or mix it up for the ride back.
Word of Warning on Old Cornelius Pass- ODOT, or someone, is doing road repair on it right now, so it may be inaccessible heading to Skyline.
Another route would be 185th to West Union, east on West Union and head up Thompson. Left on Thompson and down either Newberry or MacNamee. Have new brake pads for either of those routes down!
