Lisa pointed out to me last night that, given that I have to be in Chicago next week anyway, I should have flown there this Thursday, then flown on my own dime to Columbus to attend the World Fantasy Convention, returning to Chicago on Sunday. In effect, my employer would have paid to get me most of the way to Columbus. She's right, but it hadn't even occurred to me while I was setting up the travel to Chicago that I could have piggybacked a WFC side trip on top of it.
OTOH, I'm certainly glad that I did not need to travel to Chicago yesterday! Whew, what weather!
