Proud Mary?

Many a song is penned in regards to wheels.  They are part of our life, and have been around forever.  In the country of YAP, stone wheels were once used as a monetary/status symbol.  The wheel was used, in it's earlier forms for Fred & Wilma Flinstone as well.  Getting from point A to B, the wheel has served us well.  These steel wheels, once part of the Union Pacific saw the vast expansion of the great southwest, and also in delivering passengers from Arizona to all points east.  As a pioneer, the wheel helped forge the great expansion of the United States.  This antique rail yard in Flagstaff, AZ allows us to admire and dream about the gallant purpose of train wheels and their mighty force.
