Just joined the forum today. I've decided to take a long, lazy cross country trip from Knoxville, TN to Menlo Park, CA. My plan is to go to CA from Knoxville by I-40. I've lived in Menlo Park for years, so the San Francisco Bay Area is quite familiar to me.
I'm looking for suggestions for things to see on the way out. I've traveled all over the world -- a lot -- and I've crossed the US dozens of times by plane but never by car.
I know that I'll go see the Grand Canyon, which I've never seen. But I'd love to have suggestions about other things to see along the way. Taking side trips off the I-40 isn't a problem, though I don't want to go extremely far off the route.
Then another big favor I'd like to ask is a recommendation for a different route back to TN other than I-40 and some sights along that way.
I welcome all suggestions.
Thanks in advance,
