We’re hoping the rain stops in time for the trick-or-treaters to make their rounds. The house is decorated, the jack o’lantern is a work in progress, and I still have to buy candy. Didn’t want to do that too early. 
I’m planning an evening of handing out candy and watching a marathon of Buffy and Angel Halloween episodes (Halloween, Fear Itself, All the Way, and Life of the Party, if you’re interested). And maybe a rewatch of the Castle Halloween episode Vampire Weekend. (Hulu has it here.)
What are you doing tonight?
