Hi! I am planning a road trip from Memphis to San Diego this summer with 3 teenagers. I am planning approximately 5 day to get there and 5 days to get back home with a week in between visiting my son in Coronado, CA. I plan on taking the "Northern" route from Memphis to San Diego, and the "Southern" route on the return trip. Looking for fun and quirky roadside attractions that won't be too time consuming and natural wonders, points of interest, etc that are a must see. We are definitely detouring for the Grand Canyon and the Painted Dessert. Any other suggestions would be greatly appreciated. Also any fun, quirky or must see diners, ice cream shops, etc that are not too expensive would be awesome. I want to make this a trip of a lifetime for my teenagers with lots of fun, laughs and surprises.
