Just remembered, we tried that indoors one time with them turning out the lights. I nearly knocked myself unconscious as I attempted a save in the dark and smacked my head on the post. I'd lost my bearings and taken off for a dive about two feet away from the post. Therefore I smacked headfirst into it just as I'd reached full power for the push off and split my head open. We didn't do that again.
My own slice of the internet is here: http://www.maulsquad.com - it isn't very good.
