We drove through Wyoming when we went to Yellowstone a couple of years ago. I have to admit it was one of the most boring drives of my life, and I hope to never have to do it again... BUT we did find an awesome little pizza place that made it all worthwhile in Laramie, WY. LOL It's called
Grand Avenue Pizza, and we thoroughly enjoyed it.
Honestly though, we weren't looking to do touristy stuff, so we just drove straight through. There really wasn't anything to see. I'm sure if we'd had a more structured trip planned, we would've enjoyed it more.
