This is an amusing personal thread. I don't much care about unicorn hunters one way or the other, and i'm a little surprised to see one get more attention than all the other unreplied unicorn posts. While they probably won't find one without some tremendous luck, it's still their right to look.
PS - tons of people here are looking for something rare or unattainable. Let them go about their business daydreaming. No one is being harmed by it.
