Halloween on a Saturday is like Christmas for Sixth Street, which once again will be the site of the city's biggest gathering of ghouls, zombies and Michael Jacksons (our prediction for hot 2009 costume).

Thousands will stroll up and down the closed off street in the annual parade of superheros, vampires and all manner of dress up attire.

If Sixth Street is too much for you, check out our roundup of other Halloween events, some of which are tonight and Friday, making this a thrill-filled weekend.
