Nonexistent. Instead of commuting I got to scramble around at home halfdressed in bike gear (shorts, tights, bra) pandering to my 12 yr. old son who may or may not have swine flu and is in bed looking sorta pleased with the whole thing, digging out our very seldom used thermometer, and subsequently removing all the bathroom furniture and chasing, sweeping and vacuuming up microscopic beads of mercury from the bathroom tiles. I fully understand that poetic term of "chasing quicksilver" now - dang, they're fast!
I better get some clothes on and go buy a new thermometer...
