RIP Frank.
Damn, that's 3 we found out about in 3 days. One was an old neighbor that was a Michigan State Police Sergeant, spent a lot of time at their house growing up as all 3 boys were my age. The other was an old Michigan DNR friend I worked with at the state park nearby for many many years. Spent a lot of time in a hunting camp with him over the years as well and was just thinking about him when we ran into a friend who gave me the news.
