The ride home proved that my conference travel curse is still in effect, though it seems to be lessening each year since Detroit. (Though that may just be because it's difficult to top being sick with a 103-104 degree fever, double ear infection, and throat that feels like one has just gargled with razor blades & broken glass while giving 5 hour-long presentations over the cource of a 4-day conference, and then getting stuck first in the waiting area and then in the airplane and then in the waiting area again and then in the airplane again for several hours because one's destination airport is totally closed due to severe weather.)
More details later. When I have amassed enough brain processing power to compute.
