What if no houses are present? Obviously the bigfeet can't slap something that's not there, do they slap whatever dwelling is common? Yurt slaps, Igloo slaps, single family ranch style modern architecture slaps?

Let us know how your investigation goes. I'm skeptical about Bigfoot but I know a lot of people I trust completely that have had an experience and have seen stuff that's tough to splain....without the addition of windowpane.
