Can anyone suggest a route for a 2 day ride? Google maps says either the I-90 corridor using side roads & Iron Horse Trail, or a combination of Hwy 410 and forest roads. I live in Arizona, so I don't know the riding conditions on either route. I have heard the Iron Horse is gravel, so that sounds like a road bike with 23mm tires is out. Google Earth seems to show some form of pavement on the entire southern route, but no towns.
My main concerns are:
safety re: car traffic - so either closed trails or safe roads
food & lodging near the pass
what tires / type of bike to use - I can build up anything required
