On to South Dakota and the Black Hills area.  On the way there we fell victim to the dozens of billboards promoting the Corn Palace.  The building is decorated with various colored corn cobs each year then lure in unsuspecting tourists to buy corn related souveniers.  We got some corn cob holders.  Badlands National Park always impresses.  Next up, the Black Hills and Mt Rushmore.  That night we had a solid lightning storm.  The next day we visited Wind Cave- the very same cave where as a child, my Dad broke wind on a guided tour as the Ranger was demonstrating to the group how dark it can get in a cave when all the lights are off.  One of our fondest family memories.  Next we stayed in the heart of the Black Hills and did some trails to various peaks for great views of the surrounding rocks.  A definite must do if ever in the area.
