Oh my gosh, have a safe, wonderful, fun trip.
My son & I did that this past September. We drove from PA to L.Vegas, NV. I too thought it was a trip of a lifetime. Unfortunately, we didn't get to make many stops cause he had a time frame when he wanted to get there. Saw a neat state highway sign in OK that had the name of the city and said "Home of American Idol Winner, Carrie Underwood".
