They are only two states away, but at opposite ends of those big Prairie states. What I am trying to say, is that the distance between Rapid City and Topeka is a little bit longer than I expected. Most of it is on an interstate, so the 686 miles will pass at a pace of 67.3mph. I will spare you the math, that’s a 10 hour drive.
I don’t want to sound too overdramatic, but this drive will be a race against time. An area of low pressure moving out of the southern Rockies is headed right toward Topeka. Our route will go north of the northern most fringe of the rain and then east of the easternmost fringe of rain on Thursday. The rain will finally reach Topeka after midnight on Thursday, which means our drive will be dry, but our day in Topeka will not be.
