At the LDS Church History Museum in Salt Lake City they have a covered wagon fitted with a device, apparently designed by Brigham Young, that counts the miles the wagon traveled.
I remember the device used a number of wooden gears that eventually reduced the number of revolutions of one of the wheels to a meter which recorded the distance traveled in miles.
Wish I remembered more about it. I was kind of fascinated by it the first time I saw it, but it's now been a couple of years since I was last out there to hit the slopes.
