I took my studded tires off tonight. It took a couple hours to get it all switched and I ripped up a tube in the process.
If the entire nation is blanketed in an inch of ice tomorrow morning, it's my fault.
I also changed the battery in my cateye and re-set it. I guessed at the mileage but I think I'm pretty close. It quit letting me cycle through the readings 200 miles ago (3 weeks) so I estimated my mileage based on what I remembered plus calculated from the last time I wrote it down (October). I came up with 8550 +/- 50. Close enough.
