Yup, I was born and raised in Coggon, about half way between Cedar Rapids and Manchester on Hwy 13. Total pop. back then was around 650 people. Of course it's been a LONG time since I was up there, and memories tend to be embellished in your mind with the passing of time, but as I remember it was a great lake with plenty of room for water skiing, boating, fishing, etc. I'm sure there is/(WAS) a lot more boat traffic on it nowadays.
I was talking to somebody on FG about the Wisc. Dells the other day, called up the website, and said "Man, it didn't look anything like THAT back when we used to go!". Maybe a similar scenario.......
