The number of sites you visit Postie, it's possibly just statistical likelihood that you'll have at least some odd experiences ;)

I'm totally not denigrating the experiences here btw, I've had the odd bit of Weird Shit happen, though I've never seen anything as such that I couldn't come up with an explanation for.

Anyway, it's not the Flying Saucers you can see you want to worry about, it's the ones that are right in front of you, but invisible that are more of a worry.
