We’re a little slow-moving over here in Brokelyn HQ today thanks in no small part to the free Sixpoints jumbled up on the Mustache Ride at yesterday’s honky tonky, good timey Brokedown Throwdown. But with Halloween coming up and all, it’s a good time to point out this Craiglist freebie that could help you protect the impending zombie apocalypse: someone in Cobble Hill is giving away 15 sandbags they bought for Irene (overkill much?) but never used. The 50-pound bags are brand-new, so you can stock up for the next ‘pocalypse, be it snow, zombie, flood or occupiers.
