Today is 11/11/11. Yesterday I went to the bank for my wife during my lunch break. It's a 6 mile round trip.
Last night, on my way home from work, less than a mile from my house, the odometer on my car rolls over to all ones (111,111.1).
Had I not gone to the bank yesterday, at some point on my way to work today, 11/11/11, my odometer would have rolled over to all ones.
How freaky would that have been.
