Are We There Yet? Happy 162nd Birthday, Odometer!

Crafty Mormon pioneers first put an odometer into use on this day in history all the way back in 1847. William Clayton noticed that 360 revolutions of a wagon wheel equaled approximately a mile, so he attached a red flag and counted its revolutions. Anyone who has been stuck in a "time out" and forced to count to some insanely high number (my son would argue that 10 would qualify) can tell you that such a task gets old very quickly. Mr. Clayton discussed things with a few of his wagon train buddies and the roadometer was born!
