when i was up there we found some at Reeds in Walker MN, plus when we were up at the Sportsman's lodge we stopped at a gas station just down the road... i can't think of the bait shop/gas station.
we had luck with the "pink" colored ones. they are like a long octagon with a treble hook on the end. can either jig them or have them as a set line. both worked for us. they also do have the glow in the dark feature.
C'mon guys Save your money and put it into a Red and glow Gem-n-Eye! Twice the jig for LOW! Better yet just watch the weather. Stable weather catches fish on LOW. Dont forget a glow hook and a split shot. Pound for pound has also caught more fish on LOW.
