CLUE #12
From tiniest acorn to mightiest tree, get ready to embark:
The jewel's in Minneapolis, in a park within a Park;
Find the sum of the numbers in—and coordinate by two,
With odd clues north, and evens west—the third line of each clue.
There's no doubt that the spot you seek is a beloved place.
A great park for a nature stroll, or to train for a faster race;
Now you know the grapes of wrath are stored amid our rhymes,
So flip your lid and grab the jewel, and celebrate good times!
