...I've found the state's Masonic homepage, but either the page is down, the link isn't current, or my server is just not working well tonight...
They invite you, there's a secret initiation, you learn a secret handshake, and voila' you're a Mason.(Thats the short version) If you're a Christian, or a Catholic(last time I checked with a Catholic friend) it is frowned upon, to put it mildly.
