Cities like LA are freeing. You can wear whatever, do whatever, say whatever and no one really pays you no never-mind. No matter what you do it's likely there will be someone around who's acting even more crazy than you.
I don't know that I would want to live there. Traffic is kind of a nightmare. Where I live I can get across town in 15 minutes unless it's rush hour. Then it might take me 17. But - the opportunity to see and do things is nearly infinite in LA.
I do know this. Next time I visit I'm going to check David Markland's blog, CreepyLA.com - The Los Angeles Halloween blog - before I go.

Even if you don't live in LA you can at least catch a glimpse of the haunted happenings. And, best of all - you don't have to fight traffic to do it!
