First bigger LAN was in one of the upstairs (ground level) rooms at the (then) Holiday Inn in June of 2004 and held 100 people. I remember this because I was moving into my first apartment the day after. I wasn't staff for this LAN, but have been for every other one. Man, a history page would take some thinkin' to remember.
To go waaaayyy back.....before we had these large events we were just 20-30 guys in a basement in Port Trevorton, PA. None of our "founders" are involved any more, but I've been around since the third "small" LAN (second one held in Port Trevorton) since 2003.
