Public transporation was a nightmare this morning. I waited a half hour in 3 degree weather for the bus, which when it arrived was packed to the gills. Now, savvy CTA rider that I am, I know if one bus is that late, there will no doubt be a half-empty follower no more than one or two minutes behind. Usually my theory is correct, so I waited. And waited. And waited. I hate to waste the money, but finally figured taking a cab would be no doubt less expensive (about $20) than having my frozen toes amputated. I was still ten minutes late to work.
