I should have started some rumor like the state parks do about old ghost towns here in Cali. They have started rumors that if you take something from a ghost town you'll have bad luck. They have this story about some guy who took an old square nail from the ghost town Bodie in the eastern Sierras and "mysteriously" died several days later.
I should start a rumor that if you keep a WS geocoin for too long you'll grow hair on your palms. Oh, wait, I think that one has been taken, well how about you'll go blind then! Wait, that one is taken too. Alright, how about this one, if you keep a WS coin for too long you'll wake up one day, and Swede will be in the bed with you in a thong.
THAT should scare the crap outta ya'll!
