Traveling in the Rain

When we left Iowa this morning, it rained a bit.  This seemed to be a nice change.  Maybe it would indicate that the cool weather was returning.  We travelled for a few hours with another RV.  We made a brief stop at a rest stop.  And our friend indicated that he thought our car was most dirty.  As was his!  I started to disagree.  But, I looked more closely.  The car was filthy.  Note to self, do not put the car through a car wash the night before you will be travelling on hot dusty roads.  Or roads with lots of construction.  The end result is… Well the end result is the same dirty dusty car!
