True_Metal, no, the star is point-up, not upside down. I do know that Wiccans (witches) believe it to be a sign of power, for wisdom and strength I do believe. It is an old symbol, sometimes given the name of "The Sign of Solomon", but I've read that it dates back further. My memory ain't so fresh on it, and I can't remember where I read about it before, so if I'm wrong, let me know. It used to creep me out, the first couple of times I seen it, but you get used to it. Anyways, I plan on going back there sometime to check it out....it's cool seeing history at your feet.
