Just hit Cheyenne tonight (after a few days in Denver), going up to Casper tomorrow (19th) to stay for the eclipse.
There's a lot of media on the eclipse and a fair buzz around as you talk to locals about it. There's warnings on the highway to be prepared for extra traffic.
Here in Wyoming, all hotels for over 200 miles radius are booked out for the weekend/eclipse. According to the hotel receptionist they're banning trucks/semis from the interstate highways on Monday as they're expecting so much traffic.
Should be interesting.
