I was googling something to do with my middle-ages reenactment, so I type in "SCA" one of the hits that comes back?
Established in 1977, the SCA is the oldest national organization devoted to the buildings, artifacts, structures, signs, and symbols of the 20th-century commercial landscape. The SCA offers publications, conferences, and tours to help preserve, document, and celebrate the structures and architecture of the 20th century: diners, highways, gas stations, drive-in theaters, bus stations, tourist courts, neon signs, and a lot more. A one year membership entitles you to four issues of the
News, two issues of the
Journal, other special publications, and invitations to special SCA conferences and tours.
