Sci-Fi Saturday: The Hardest Sell

Subsidence made a sinkhole near the edge
Of this small town, just where folks go to see
Our  finest mountain vista. Now, I pledge,
What happened's no one's fault, and it's now free
Of all remains, but I'm afraid it's true:
The site was not updated, not online.
So tourists, on those smoggy days, those who
Had VR sets that always showed a fine,
Clear view, and used them... Yes, they fell
In frightening numbers, down the slope, and yes,
Some died. It took a while for us to tell
Where lay the problem, but I do not guess
You care 'bout that. Best buy my software patch.
I saw the problem, and fixed it from scratch.
