What is a mason?

I watched a long history channel special on it last week or two weeks ago. I was interested because my son is a mason, or freemason (the old fashioned word). As near as I can tell, they are now a club of men (the women have their own club) with ancient secret rituals.

George Washington, Benjamin Franklin, and many others were masons.
