go to an Atheist or Humanist convention

So, the trick is to find the right conference or convention. There is a National Convention of American Atheists, but there seems to be some things that might be a little offensive. They talk about pitching Gideon bibles down the laundry chute, which might just be fun, but seems like a very divisive thing to do.
I might have more luck with a Humanist conference, but they seem to be a little more expensive to attend. The last one was in Paris, which is a bit of a trip.
I’ll just have to keep my eyes open for the right one.
