Have you ever done a big road trip where it feels like the same road just goes on and on and on? The longest highway in the country is not part of the major interstate system. It still runs through 12 states, including Idaho.
The building is fascinating to look at and if you are able to carefully see in any windows you can see dusty antiques all over. Idaho in 91 Days describes it as, "...it’s among the most eccentric structures we’ve seen anywhere in the States. It is the strangest and coolest house we had yet seen in Idaho, and we spent a long time admiring it from every angle."
