A group of five of us (Jenn, Steve, Katrina, Tyrus, and Joe) attended the annual American Atheists convention in Philadelphia from March 25-27, 2005. Joe took a number of (unfortunately kinda blurry) pictures there on his cameraphone, which are posted here:
The conference took place at the fancy Hyatt hotel in downtown
Philadelphia:

The conference itself consisted of a series of interesting

explanations of religion to humorous examples of religious
paraphenelia:

Much to our amusement, the convention attracted a small group
of evangelical Christian protesters:

Finally, here's a picture of Tyrus and Jenn listening to one
of the convention speakers:
