To my ever-partying sister, they may be 'reining in' the Halloween festivities this year (which has been badly needed because they are getting explosive and out of control) in the Castro, but anyway you might look at it, San Francisco takes Halloween seriously and it is one giant, wild 'mardi gras.' I've said it before and I'll say it again, as much as you love the nightlife and Las Vegas and parties, you will love Halloween in San Francisco. That goes for you other party crazy readers out there too. I, myself, will most likely be staying away and reading something because I'm lame and old.
