The mailbox seams very mysterious, although it only recieves ordinary mail for the Medlin Ranch. For years the black mailbox has been a mecca for UFO buffs. It is a prime location to see a UFO because it is only a couple of miles from Groom lake(Area 51). It has been popular belief that the best time to look for UFO's around the mailbox is on Wednesday nights or very early on Thursday mornings. The Black mailbox is only a couple of miles from the Area 51 Research Center. This information was taken from the Area 51 Viewers Guide, written by Glenn Campbell, founder of the Area 51 Research Center and the webmaster for ufomind.
