Ice fishing is about knowing the lake. You don't want to spend the time drilling through more than a foot of lake ice only to sit and freeze, so you have to know where the fish are.
That's where the local Bait and Tackle Shops come in. These are the guys with the knowledge base- they can tell you what time of day that the fish will be biting in which part of the lake. Be friendly though, first chat about the weather, complain about the roads, crack a joke or two. The insider fishing track will come only if they like you.
