To create an ice fishing advocate, two things are necessary in my experience. First they need to stay warm and second, they need to catch fish. While your quest might be a 12 lb walleye, a fishless day will likely mean his/her last time on the ice.
The simpler it is for them to catch something (re: can be a small perch, trout or bluegill), the more likely their attention span for electronics, lure/bait selection and strategy will follow.
So I guess what I am saying is the ball is in your court. Make is both a fun and memorable day and by all means have fun.
