I don't check this web site often ---just read your question from Dec. 2011 asking if we meet anywhere in the Pgh area. Go to meetup.com. Enter "Pittsburgh" and key words such as "atheist" "freethought" "skeptic" etc. and you will find several groups that meet regularly in the area. You can also enter other key words for your other interests to find groups that may interest you.
Hi Donny, and welcome to this wonderful world of rationality, truth and peace.
True common sense helped by science leads to atheist wisdom as freethinkers know well.
We invite you to make good friends by joining the busy group "ORIGINS: Universe, Astronomy, Life, Earth, Humans, Religion, Gods, Atheism, Evolution, Darwin..." with 590 discussion topics and 3200 members.
