Mike Berlin was a very successful professional bowler from Muscatine. I remember when at ISU in the late 70s I had the TV on and the announcer says, "Muscatine Iowa" and my ears perked up. He ended up winning that particular televised event. This was back in the days of 3 channels so seemed like a big deal.
I think he also coached Muscatine HS bowling as I seem to remember an inlaw's relative was on a record setting (State of Iowa) team score event and I noticed his name as the coach. This was about 10 years ago or so, I think.
