Ten holes in Waterloo. Not nine, not eighteen. Ten. Irv Warren runs its own math and expects you to figure it out. Public golf in Iowa often means wide fairways and honest conditions without the fuss, and this one fits the mold. The walkability holds up fine for a casual loop. Nothing fancy, nothing broken. The kind of course where locals show up, play their round, and head home without needing to tell anyone about it. Sometimes that's exactly the point.
