What are the best routes?
Here is what we know; Otherwise we are wide open:
1) We may or may not want to visit family in DC before we head west. This is optional.
2) We want scenic routes - e.g., Rocky Mountains.
3) We want touristy routes - e.g., Grand Canyon.
4) We can't decide between a) cutting across through Chicago, Colorado, etc. or b) taking the Southern route through DC, Texas, etc.
I guess it's between I80, I40, I10, and maybe even Route 66?
Any details would be appreciated!!! Let the journey begin.
