I just got an email inviting me to give a talk about Hercules at the National Capital Area Computer Management Group (a mainframe users' group) - at their expense. Whee! Of course I told them I'm going. It's the 11th of February, and I'll fly over the 10th and stay the night. I'll get back late on the 11th (actually, just after midnight the 12th), but hey, it'll still be a cheap trip.
