Dream destination!

I would like to make a road trip across the USA.

It would take anywhere between 1 month approximately to 6 months.

There's no reason to rush it because it is supposed to be laid back and casual.

The car would of course be a Ford Mustang 1967-69 or 1970-1971, it doesn't matter if it's a fastback or not but I would prefer a Shelby.
