I've been in the ACM since 1986, though not very active, I mostly let my CACMs pile up in a corner and skim through them once a year. Today, though, I got invited (as I'm guessing every ACM member within 75 miles of Philadephia did) to the 2005 Turing lecture by Vint Cerf and Robert Kahn. And...I'll be in Chicago, or on the road back from Chicago, no where near Philadelphia.

Drat.
