ported the San Diego Union, "Five mysterious lights were

Ed: San Luis Obispo made news in November when it was selected
as the site for Mon-Ka the Martian to contact earthlings from his
saucer. Saucerites claim that saucers did appear over San Luis
Ohispo on the desiguated date. but autborities counterclaimed tha:
the objects seen were balloons. However, the predicted radio con-
tact never took place-and the aifair was tagned a hoax by moet tact never took place--and the aifair was tagned a hoax by moet
civilian researchers. With so much emphasis put on San Luis
Obispo, it seems in line that other sightings, such as the one of
Dec. 2, should take place and be publicized.
