Hello,
I was just at Alpine a few weeks ago.
Here is a super tip for all of the BW... Use the TOG leech method. It is basically just a small hook tied directly to your line. You can add a small split shot if you like. Hook a nice leech right through the sucker and cast it out.
Let it settle for 5-20 seconds and reel it in extremely slowly. Your retrieve is not adding the action. The live leech is.
When I was on Alpine a few weeks ago, I caught most of my fish with this method. There are not many fish that can resist a real, live leech.
As for bringing in leeches, that is also very easy. Stop at Hanks Hardware in Grand Marais. Get 1/2 to 1 pound of leeches and have them put in a Bait King leech container.
