I've made it. Though Delta lost my bag on the way there and made me miss my connection on the way back, I nevertheless pulled a Homeward Bound and fought through the hardship. The conference was great: watch Clinton's speech here, and stay tuned for my panel to pop up on the same page. Moreover, as I stood in line to board my flight back, I saw Karen Hughes chatting with someone. "Huh," I chuckled, "only in DC". At which point I promptly got on the plane, took my seat, turned around, turned around again, turned a third time, and finally greeted John Lewis.
Huge thanks, of course, to Neil, who did a bang-up job on the site and gave me the peace of mind needed to focus on the conference. He's the man and you should read him at his place.
