I hate when that happens. Take care of you. You have another trip to make!
Have to revise powerpoints for both now, but that's an easy matter. At least the critiques of my talk were both good (one from a co-worker, another my boss). I had to laugh when my boss mentioned my unusual "rest posture" though -- it was close to to my pipe band's "parade rest" position. (Most pipe bands are pretty sloppy about marching but not ours -- we practiced an awful lot to get and keep it "just right.")
