I actually stood in the end of a rainbow once --- and there is no pot of gold. It's all a hoax. Probably propagated by leprechauns to keep us hunting for their gold in almost completely elusive places so are attention won't wander to where they actually keep the stuff. *******s.
It's clear that these leprechauns are trying to kill us. I now agree with you Thomas. Just look at this prime example... how many people were killed trying to run out in front of traffic on a busy highway, looking for that 'pot o' gold'?
