We squabbled a little last night over whether it was a good idea for Charlie to ride his bike to work tomorrow (a couple inches of snow on the ground, slick roads, cold temps). I made him promise to ride his bike on the sidewalk if he did (no shoulder or room for cars to manuver around him was my thinking...). He reluctantly agreed.
Then the temperature dropped to -4 this morning. He was pleased to have a ride to work, I think (he certainly didn't argue!).
