Don't know about the ice at Swan...it is probably like the rest of the lakes around here...2-4 inches. A lot of lakes have spots of honeycomb which makes them unsafe. I fished Sugarlaof last Sunday in close, then a kid went through on Monday chasing his model airplane. I tried to go deeper on Wednesday but it thins out fast. The recent snow has not helped.
I'll let you know about the Pike tournaments. A guy named Rich is in charge of them.. he is somehow connedted to the Party Store/bait store at Mersons Corners. I don't know the name of the store but I'm working on it...let ou know then. All tournaments are on lakes in Allegan County. Also there are Musky in Swan...I think they combined Pike and Musky last year. It usually costs $10 to enter and $5 for the optional "side" contest...usually bass (released quickly), walleye or musky. Payout is for the first 3 places (biggest fish) and one payout for the "side". The tournaments are 100% payout. There is a raffle at the end of the tournament..prizes have been everything from ice shanty's, filet knives, augers, poles, buckets to a handwarmer.
It is a good time...Rich(and his wife) do an excellent job. More details later.
