Casper, WY

Passed through Casper, WY on our way to I-90.  We have about 235 miles to Sturgis.  We won't make it to Sturgis tonight but will still have time to go to Mt. Rushmore and Crazy Horse.  Weather has turned cold but no snow other than on the mountain tops which is good.  I have to put my flip flops away and get my tennis shoes out, UGH!  I am also probably going to have to buy a couple sweatshirts as all I brought were T-shirts.
