Tour of a PSP house?

I live in north Idaho and I was wondering if there is anyone who is within driving distance of me who has a PSP earth sheltered or earth bermed house that would be willing to give my family a tour?

I plan on building a PSP home. I have read up on alternative housing for years, so I have no problem visualizing what the end product would look like. However, my family has a little more difficulty with that, so I think it would help if we could tour someone's place.

Even a non PSP underground home might help with getting ideas.
