I finally got out and rode McKenzie Pass this weekend from Sisters and it was perfect up there. I wrote up a Ride Report on my site if anyone is interested in the full version: http://ymmvreviews.com/adv/mckenzie-pass-eastside-ride/. I have included at the bottom there the info from my Garmin as well. I saw a whole bunch of people up there and the rode is nearly clear. I read today that they should have it open to cars any day now so get up there ASAP if you want to ride it without cars. Such an epic ride, 28 miles round trip from Sisters, I did not have time for the over and back option but That would be a fun ride as well. The west and east sides are so much different. Here are some pics as well, more on my site.
