They're a very common bait to use on a bottom bouncer rig for walleye. Used a couple dozen of 'em this year doing that.
Yep. Buddy and I have gone through over three flats so far this summer.
What is a "flat" of nightcrawlers?
Came in small tubs where I came from.
Haven't fished in over a year, no water this year, some of the local ponds/reservoirs are dry or nearly so.
