Come see what another atheist looks like (outside of the colloquial closet). We push some tables together, have some great food and strike up conversations on anything that interests us. This isn't formal, we'll just chat about whatever we want, atheism related or not, as it's more of a meetup than a meeting.
Parking is plentiful and in the neighboring garages, though make sure you remember where you've parked!
Hope to see you there!
