Another Time Zone

We're now in Sioux Falls, South Dakota and 2 hours ahead of you all except for our Ontario readers.  Started out from Spearfish about 0800 this morning and just spent the day driving.  We are now in the south eastern corner of South Dakota and heading south through Nebraska and Iowa tomorrow.  We've travelled 1604 miles from Burlington, Washington to where we are. 
The weather continues to be hot but not unmanageable.  It cools down through the night and gets hotter as the day progresses.  The countryside has been breathtaking and it is so vast it makes you wonder how people manage to live out in the middle of nowhere with nothing for miles and miles. 
Looking forward to what tomorrow brings . . .
