Ken and I found this wonderful rail to train bike route call the ROUTE OF THE HIAWATHA http://www.skilookout.com/home_bike.html and http://wallace-id.com/skilookout/taft.html. It is probably too far for you but I think you and Sara would love this so i had to share! This path crosses many high trestles and goes through a few long dark tunnels so you have to carry a flashlight but it was one of the most scenic and interesting bike rides i have taken.

Have a great trip, Amelia in Los Angeles
