Welcome to the Forum, Art. Seven pound Brookies - Wow, those were the days!
Used to catch some big pike when I was at the U of Iowa. In fact, I had a local record from the Iowa River when I was in Iowa City in the late '60s-early '70s (but I'm sure you routinely beat that size up in Minnesota). Caught my first trout in northern Iowa with a law school classmate who introduced me to them, and have never looked back.
