Halloween takes over the month of October, providing plenty of places to party and play in costume. There's a lot to do and see around the city during this spooky season; here we've compiled a list of the top twenty haunted throwdowns catering to the mature crowd. (Don't worry, we've got kid-friendly and Dia de los Muertos events lists coming your way, too.)
Those looking for something a little scarier and sexier can check into a paranormal investigation of a Capitol Hill haunt or hit several parties with big cash prizes for the most innovative costumes. You can find more possibilities in the online Westword calendar -- but this list should fill your trick-or-treat bag with a spooky good time.
