About the Container
You are looking for a bottle opener with a blue handle. Please bring your own pen.
About the Location
This is a stretch of the Kinnickinnic River Parkway, just north of St. Luke's hospital. There is plenty of convenient street parking on Dakota Avenue. There isn't much muggle traffic here and you'll be pretty well concealed when you get to GZ. The difficulty is easier when there are no leaves on the trees. This cache should be finadable even with a lot of snow on the ground. The hint has very specific information, so don't read it ahead of time if you want to hunt on your own.
Cache placement was approved by Brian Russart of the Milwaukee County Parks. Permit #375.
About the Coordinates
This is a tough area to get coordinates. I've done a lot of work to make them accurate, but your results may vary. This fence is across the street on the north side of Dakota Avenue. The cache is straight south of the red line.
The difficulty for this cache really is 1.5 stars if you're looking in the right area. If you get stuck, please resort to the hint.
