Thanks for the reply.
The places we're staying 1 night aren't places of key importance to us. I grew up near Blackwood so I'm showing my girlfriend the area there. She's got family in Baltimore so the same thing there. We didn't really want to go to Dallas but it seems like an ideal stopping point in between New Orleans and Denver, both places we do really want to see. Yellowstone might be a little rushed but I think it'll be okay. Rushmore I feel like I can see in a short period of time. Canton for the Pro Football Hall of Fame and I've heard you can thoroughly take it in in 2-3 hours. Connecticut is just a stopping point on the way home.
Those are the places I stay 1 night in... the ones with 2 nights (or 1 full day of sightseeing, rather) might be rushed, but I don't think I'll MISS things entirely.
What's everyone else's opinions?
Thanks.
