I am planning on taking a road trip, on Hwy 50, starting in CA, going to MD and then back, sometime in mid August through mid September. I've never done anything of this scale before and am looking for advice. Specficially I'm looking for advice on:
-Timing: will 4 weeks be enough?
-Sights: is there anything I should not miss?
-Anything I should avoid?
-What would be a good alternate route to return (I'd prefer not to come back the same way I went)?
-Should I rent a car or just use my own?
-Any other advice or suggestions?
