AM: C1, 41 minutes. Driver in a good mood.
PM: Expected trouble from the late night Christmas shopping, so walked home voluntarily - and caught up with class F traffic at the 5300-yard point. On my way into town I passed all 4 buses that had driven past me on the early part of the walk, and at the top of Ennui Hill, another one. Home in 77* minutes, which isn't bad for nearly 4 1/2 miles' walk.
