Thanks for this, Rubiconbob - do you remember where you saw the info about his senior year and possible military plans? Thanks so much!
I mentioned on another thread that between the ages of 18 and 21, he has zero record (not even speeding tickets). That's a pretty amazing record for a northern Wisconsin boy

Out in the country you have to drive literally everywhere on isolated roads--everyone speeds mightily--and nearly every boy gets speeding tickets, lol. So I feel it's worth exploring whether he was away with the military for a 2-year enlistment--which would mean the Army (the only one with an regularly-offered 2 year enlistment option).
The 2 year commitment doesn't begin until you're done with basic training and tech school(s), so the overall span of time always ends up being something like 2 years+some months.
