Halloween is almost here--do you have a costume picked out yet? We're going as the Purple Line extension and will be knocking on doors in Beverly Hills. Spooooky! Where should you go trick-or-treating? Well, we've analyzed your nominations for the best trick-or-treating neighborhoods in LA and broken them down into five regional categories--the eastish-side, central and West LA, the Valley, the South Bay/Long Beach area, and the San Gabriel Valley. Voting starts today in the central/West, South Bayish, and SGV categories; we'll vote on the other two tomorrow and declare the ultimate Best Trick-or-Treating Neighborhoods on Friday. Polls will be open for 24 hours.
