Halloween - Should I Be Afraid?

Let me first point out that it's not because I'm scared of ghosts and ghouls. Although I must admit to intensely disliking clowns. It's more the fear of being overwhelmed by crowds of mad people high as a kite on sugar and/or booze.

America does Halloween different to anywhere else I've ever been. It's HUGE here. Just walking past costume stores yesterday with lines to get in the store before selecting a costume and then joining another lengthy line to purchase the thing. Craziness.

And there have been specials on candy and chocolate for at least a month in almost every pharmacy I've been in. Which in itself is weird, although not as weird as the fact that they sell cigarettes, surely?

Anyway, as I head out to prepare for a (hopefully) relatively relaxed October 31st, the question I ask is: should I be afraid?
