Every June, for a couple of weeks, the Photinus carolinus fireflies of the Great Smoky Mountains flash in perfect synchrony — thousands of them, pulsing together 'almost like a heartbeat.' This year 45,000 people entered a lottery for 960 parking spots, and a four-night viewing event at $325 a person sold out. Thursday's A-hed is pure delight, and it smuggles in a lesson about scarcity.

The synchronous firefly puts on its show for only a few weeks each June, only in a few places on Earth, and only if conditions cooperate. The Great Smoky Mountains National Park got more than 45,000 lottery applicants for 960 parking slots. A nonprofit's four-night viewing event at $325 per person per night sold out. Pennsylvania's Firefly Festival has pumped roughly $1.5 million into a tiny forest region and draws visitors from every continent except Antarctica. Scientists, meanwhile, beg the crowds to behave: phone screens and headlights disrupt the mating display. As one researcher put it, perfectly: 'They're not flashing for us.'
One mother stood in the rain for an hour with her kids, ready to call the whole trip a bust — then the forest lit up, thousands of beetles pulsing in sync, 'almost like a heartbeat.' That's the whole product: you can't stream it, can't skip the line, can't buy a better seat. You show up, you wait, and sometimes the lights come on.
Why does a $325 bug ticket sell out in a world of infinite entertainment? Scarcity, seasonality, and the fact that the best things compound quietly until one night they all flash at once. We spend our weeks writing about transformers and basis points, but the firefly economy runs on the same physics as a retirement account: the reward goes to the people who showed up early, stayed patient in the rain, and didn't spook the compounding with a flashlight.
Also, practically: if you want to see them, the lotteries open in spring, the Smokies window is early June, and the Pennsylvania festival runs late June. Book the cabin a year out. Some assets you ladder; some you lottery.
No tickers, no trades — this is the one you read on the porch this weekend and forward to the grandkids you're about to take camping. (If you want the portfolio version of 'scarce, seasonal, and worth the wait,' that's the rest of this week's edition.)
