I know what you're thinking: there isn't any good fishing in the Ministik.
Jonah bet?
If you continue past the Waskahegan Trail sign staying on the road that eventually leads to the U of A Ministik Wildlife Research Station gate, you'll see a small meadow on your right.
The meadow may not look like much from the ground, but look at it on OpenStreetMap:
It's a huge fish, complete with the cheeky addition of an eye by an OSM contributor who shall remain nameless.
Have a nice walk along the road and if you're feeling lucky, or just for the halibut, continue on to find a few more caches on the way to the Research Station gates.
