It's the mid-1970s, and it's a very important time for this group of teens. Throughout the year they'll be trying hard to snag enough credits in order to graduate. But even more pressing is this often-underrated task: Having their senior photos taken, and deciding which one they should submit to the yearbook.
The high school I attended in the late 90s was strict on what senior photos could look like in the yearbook. They even had restrictions about the dimensions of your head. No hats. No slogans. Neutral backgrounds. OR ELSE... or else, uh, they'd just end up using the Jostens photo they'd snapped of you on the first day of school.
Daryl Minton had a rare condition where he could only grow out his mustache OR his sideburns -- one a time, but never both at once. So he had to make a decision. He chose the sideburns, and he has never once regretted it.
