Yes, Houston is having a Horror 48HFP in October also. I'm trying to decide if I want to do it, Horror is not a favorite genre of mine. There are 26 total horror genres (list below), of which each team gets two to pick from. I dunno, still mulling ... I've got till 10Sept to sign up at the low early bird price.
