Area 51 Research Center
Now closed down, until a few years ago this trailer was jam-packed with information on the nearby secret base (the Groom Lake Base, located inside Area 51 of the Air Force's Nellis Range Complex). The Research Center was founded by Glenn Campbell, the independent secrecy-watchdog and UFO researcher (who, in some circles, is now better known than the singer of the same name). Campbell retired from his pioneering Area 51 research in the late 1990's, and the Research Center was later operated by other people. The nearby Little A-Le Inn, one of two commercial establishments in the tiny town of Rachel, has more speculative UFO-related information and serves hamburgers.
