Last Days Landfill Limericks

This lore I tell may be known by few,
But the puzzle is truer than true.
I’ve set out on my quest,
To resolve this strange jest,
With determination, I’ll find what’s askew!

At landfill prairie I roamed with dread
The mystery swirled round in my head
At last, like a flag,
A twenty-nine tag!
I grabbed it and onward I fled.

The field has been a wonderful friend
But my time here has come to an end
With joy I confess,
I’ve fixed up this mess,
Leaving others no doubt still to mend.
