2019 TC Treasure Capture The Flag Mini-Hunt

Please forgive us for the early morning wakeup call;
Our mini-hunt has started, though, so hear ye one and all:
Pay attention to the signs and search in a careful manner;
Start at the very beginning if you wish to seize the banner.

Be the one to bear the standard—the target of your vigil—
Emblazoned with a ten-year-old design that forms its sigil.
Research the community (as with all treasure hunts);
Make like Walt and find a way to go two ways at once.

Now, for all you history buffs, and fans of local beer:
Eighteen hundred ninety-one was surely a banner year;
Search for the prize near benches in a row of bushes and trees,
Within clear sight of letters and numbers blowing in the breeze.

Make your way to a lovely park in the home of a former Saint,
Proceed to a sign with letters carved in wood, with fading paint.
Listen closely, research well; your victory's in the cards:
Sven Ivan O'Myron Wisnewski sends his very best regards.

Meander through Twin City Sidewalks to a noteworthy parking lot,
And quickly amble northeast-bound to the treasure's hiding spot.
It could still be there waiting—that is, only if you're nimble—
Now hurry; go and grab the local flappable civic symbol!

Deposit yourself on the northeast side to make a small withdrawal,
In the shade of a bush at the base of a tree you'll find the treasured haul.
Right near the park sign in an ironic can—don't let it go to waste;
To the northeast bank of the northeast bank on the northeast bank make haste!

SECRET CLUE
(Given to hunters who contacted Johannes during the hunt)

The treasure's hidden; the flag is furled; it's cozy in its nest;
Flagpoles could prove helpful on your vexillological quest.
