Americans, do these sound like good road trips to you?

Those sound great! You're only hitting the west coast though! The east coast is pretty awesome too. I've been all over the U.S. (I live there) and I personally love Chicago, IL. It'd be a fun stop to incorporate. And if you are looking at east coast stuff I'd say Maine is a fun state and definetly New York. Anyway, your current set trips sound awesome, they'd be a lot of fun for you! Good luck on setting them up and have fun!
