There's so much to do in this lovely state, but you might start by...
admiring the buffalo at Custer State Park
visiting presidents here (in Rapid City with John Adams)
You can also eat buffalo ribs
support Lakota artists and the Crazy Horse Memorial
and visit funky places like the Corn Palace, where yes, the place is decorated in actual pieces of corn!
But THE BEST PART I am saving for next post. :)
