Day 2 - Salina, KS to Wall, SD

Random wandering a of the mind-Simon & Garfunkel's song "all gone to look for America" kept running thru my head.  Another day of pointing the car north, but today with occasional stints westward.  Once we got close to I-90, the views were of wide-open spaces.
Wall, SD has a 2 block business  area, of which half is the famous Wall Drug.  Interestingly, moat of the store workers seem to be from impoverished countries - Macedonia, Poland, Jamaica...  Guess there aren't enough locals to handle the tourist season?
At any rate, we are now in The Badlands and will see them up close tomorrow.  Butch Cassidy and Sundance?  Wild Bill Hickock?  Bury my heart at Wounded Knee.
