Ephemerisle 2010
This year, The Seasteading Institute officially abandoned the event about a month before it was to begin because the insurance costs turned out to be around $300/person. As a community, we decided to show up anyway and create an unofficial self-organized event, branded "NotEphemerisle". Despite the lack of central organization, it still worked quite well, and around 120 people showed up and had a great time.
Besides recreational activities, the event also hosted 12 "Memocracy" talks.
