Hmmm... Best month (34 + 4 * 3 * 13) = 190. (7 years ago on my navigator)
The last month: 3*28 + 9 * 4 *3 = 84 + 108 = 192... TADA. New high.
Of course, this is approximate. Keeping records is something I don't care for, but I can get a pretty good idea. The last month is definitely an all time high for me. (I just remembered another 9 miler and a few other short jaunts.

)
Methinks a nice GPS system is called for. I wonder how simple it is to just turn it on, log my ride, and upload the rides on occasion. Lazy, I know, but it would be sweet! Anybody have experience using GPS for logging miles and routes on a daily basis?
