Okay,  so apparently, despite the fact that Halloween is Saturday, Halloween will begin early in Cambridge with a “Monster Mash” parade in the Square and lots of mimes and people in costumes performing for your enjoyment. The target audience is admittedly for the “I think I’m ready to get out of diapers” crowd, but if you click here you can scrounge out some sweet deals compliments of Halloween that are currently going on. For example, Baskin Robbins has Haunted House cupcakes. I don’t know how that works, but I want to climb in one and eat my way out. If that’s not your thing, Curious George is making an appearance in the Square to read to you and the kiddies. The festivities begin at 4 p.m. and will wind down around 8 p.m. I would recommend wearing your most scantily clad costume to create an interesting juxtaposition with all of the kids dressed as Winnie the Pooh. ETC.
