2013 YTD Mileage - Reconciling the Subledger

I will admit that it is a little strange to report numbers in the middle of a month, but I am afraid if I don't get them out there I will lose the data forever.  Granted, if I compare these miles against my total anticipated mileage for 2013, they will be mere rounding errors and are hardly material.  But it always bugs me that I have so much off-ledger miles that don't get recorded that I wanted to make sure I kept track of them all in 2013. 

Through February 18, I have ridden 56 miles.  Of those, 27 were in San Diego on a rental bike, and 28 were from two separate rides in Minneapolis.  Once enough of the snow had melted (or been plowed) to clear a safe path, I ventured out for some invigorating winter biking.  

Normally I wouldn't have to resort to updating a sub-ledger as I usually install a bike computer on any new bikes.  However, when I bought the Cross Check to commute with, I never got around to outfitting it with a computer.  Since most of my miles in the fall were on the Cross Check, I have a hard time seeing how anyone could do anything but issue a disclaimer of opinion on the operation of internal controls over bicycle mileage reporting.  I guess remediation will have to happen in 2013...
