“You know what would be really cool?” asks Troglopundit. “A prime number made up of a prime number of digits.”
On his second thought, he revised his adjective, from “cool” to “nerdy.” But by that time, I’d come up with a cool/nerdy notion of my own: “Prime Park,” a single-street gated community somewhere in the ‘burbs with half the property the half where even-numbered houses would go reserved as parkland, and the houses opposite the park assigned prime numbers consistent with the area street grid. For instance, the 3000 block would run 3001, 3011, 3019, 3023, 3037, 3041. (I figure that this subdivision, so to speak, would likely contain imposing, overly-large homes, and that maybe six to the block is pushing it.)
Passersby outside the gates, of course, would never know, at least not until Google Earth showed up.
