First, almost couldn't get the frozen bike rack down (when not in use it folds up).
Then my chain froze during the bus trip home --I know, a better lubricated chain....
Finally, though okay on level ground, with the slightest incline I had no traction, even with mountain bike tires.
Fortunately, just at that moment, bus #49 came along. It goes up the hill and then to within 5 blocks from home. This violates my rule of not taking more than one bus per trip, but hey, as an LA Times columnist pointed out, we're "clueless" when it comes to snow.
