"The majority of the basement is covered in black mold and in biblical proportions," says this listing found by Matt. And I have nothing contumelious to say about it, because they've been admirably honest in the description. "Not for the faint of heart or respiratory system!" -- well, there's just no improving that, is there?
So maybe sometimes people do things just right. And we don't mock them. We just sit back and stare at the mold in awe... and wonder how that house ever ended up submerged in a canal.
