An event (Regional Burn), group or organization created by Burners somewhere other than the Black Rock Desert. Burning Man has made efforts to control who can officially call themselves a regional representative, or which events are official regional burns, but no one pays them any attention. Regional Burns allow you to meet the same person more than once without a GPS unit and a tracking device, and may feature such luxuries as swimming holes, natural shade, or even actual showers. Someone who is Burnier-than-thou will tell you this adulterates the valuable, character-giving experience of sleeping on the cement-hard playa in the dust after the 50-mile per hour winds obliterate your tent.
