I spelled out (hmm, is that correct English?) the front page of the May 24 Issue of the Montana Standard, but I did not find any relation to Pony.
So: why "maybe May" David?

Thanks for your keen observation Dave!

The poet Richard Hugo wrote extensively about the dead and dying towns of Montana (he taught at the University of Montana in Missoula). Several of these poems were done in the style of letters to friends, including the one he wrote about Pony. Here are a few lines:

Lovely old homes stand empty because somewhere
in this floundering world, the owners toil and plan to come
back here to die. I want to die here. I want to spend my
last years on the porch of the blue house next to the charming
park the town built and no one uses, picnic tables ringed
by willows and the soft creek ringing in the grass

and elsewhere:

... there still is a place where the soul
doesn't recognize gravity, where boys catch trout
and that's important, where girls come laughing down the dirt road
to the forlorn store for candy.

It doesn't want to turn over.

Pony apparently avoided true "ghost town" status, as it is still a community in 2025 (population in 2020 was 127). Looking at the town on Google Maps, I see a few businesses, a bar, a bank, and a U.S. Post Office. So not dead, although it's not exactly a thriving metropolis.

Looks like the older structure above the car fender on the far left side is still there:

... but from a different angle.
