You don’t even need to rig them. If your on the south shore and have access to a pontoon. Head for the mid lake gravel and find the tops of any structure in 20 to 30 feet of water. Anchor and bobber fish them with a plain red hook and a leech. You can drift them with a lindy rig but if your dealing with kids, just a slip bobber will be fine.
In the evening hours, anchor out on the same flats or gravel flats and do the same thing, Slip bobber, plain red hook and a leech about a foot off the bottom should produce fish for you.
Quick update. Tried a few different things. Son caught one 26.5″ Walleye off the shore near the marina with a paddle-tail. Then we did the above for a few hours and caught 4 walleyes and missed one other. Tried to get on some small-mouths but never got any action which was disappointing as the time between walleye bites drug on a bit. All in all happy with the trip and would try again. Thank you again for the feedback.
