Here's a route without going on the interstate. I can't tell you anything about its safety. It looks interesting and is about 457 miles. I used the google walking directions engine to create it. Switch to "hybrid" and zoom in to see more.
*** EDIT NOTE ****
Hey all, I do apologize, the LA to Grand Canyon route, previously posted, has been removed as it is potentially dangerous.
