LAN party that I witnessed (but did not participate in)

This is the wikipedia definition of LAN party.
"...A LAN party is a temporary, sometimes spontaneous, gathering of people together with their computers, which they network together primarily for the purpose of playing multiplayer computer games. These local area networks (LANs) come in various sizes, from very small (two people) to very large (more than 10,000 people). Small parties can form spontaneously, but large ones usually require a fair amount of planning and preparation on the part of the organizer..."
