These situations are more common than you might think. When I taught at the DeVry school in KC, I was lecturing in Kansas and Missouri at the same time. The state line cut through the middle of the building.
Some of the science items are outdated now, but all were accurate by the knowledge available in the '30s. Marconi didn't invent wireless details the earlier history of radio accurately.
Here's a genuinely strange sciency item:
A floating island. Is it still there? Yes.
The pond is very clean, has a small beach reachable only by boat, is virtually deserted on week days, has New England's only floating bog, there is a profusion of wild life, including great herons, and there's excellent fishing.
Googlestreet catches a pretty good view of the quage:
How does a floating island maintain itself for decades while drifting around the lake? Is there a giant fungus holding the trees together? Does the fungus paddle its quage to find better food supplies?

Language sidenote: One modern reference to the floating island says that "locals call it The Quag". I suspect Hix misspelled the odd word, or else a local informer misspelled it. Looking it up, quag is an old word for bog, normally seen only as part of quagmire. A quagmire is a bogbog. But I like quage and decided to keep it as a precise term for a floating boggy island.
