Casper's normal population is around 60,000. The estimates are that it will double for the eclipse. This may be an under-estimate.
Casper is on Interstate 25...the same Interstate that runs through Denver and the Front Range of Colorado. I reckon there are at least 2.5 million people within 4 hours drive of Casper (when driving is good). Fortunately, there is a good stretch of I-25 that is within totality, so maybe those people will just pull over.
Craig, you are coming from the North and may not see much traffic!
P.S. I am going to central Oregon. As far as temporary population growth, it could be worse than Casper. It's just that I have friends there on totality; so, insanely inflated hotel/campground prices and driving on the day are not an issue.

I am going to make base camp at The Devil's Tower and commute to totality for the eclipse. Planning to be there about a week before the eclipse. I didn't realize there was an astronomy event in Casper while I am there... I may have to work that into my itinerary!
