I know John is on the busy side of things right now, so I will give you a hand. This is from Johns post on March 11, 2008.
"From MSP we traveled to Mankato on 169, then took 60 to I-90 at Worthington. Took I-90 through SD & just before you get to Rapid City, took 79 south to Hot Springs & then took 18 west into Wyoming & down to Lusk. Stayed on 18/20 to I-25 & took that to Casper. Then picked up 20/26 7 took that west toward Riverton. We did not drop down into Riverton, but took the little by-pass on 134. Then took 26/287 up to Dubois & Togwotee." Any Questions, "Just Ask John"
