I'm cool any of those days.
However, my boss just talked to me about going to Korea during the week of Feb 20, so I don't know if that would impact one weekend or the other. At this point, though, I believe that I have successfully fended off the trip. I've been there once before, and I met with some people who reported me to the authorities (for totally bogus reasons, but they were very, very pissed off with me because I'd embarrassed them and taken business away from them). My boss wasn't overly moved by this story - pissing people off is what we do best, and we take pride in that. He did take note, though, when I pointed out that those people and the people he wants me to meet with next month are the same people.
