Throw-in confusion

[BillyMac]

We have few high schools in our area that had, or still have, endlines and/or division lines that can be confusing for officials, I know, I've had several inadvertent whistles over forty-plus years.

Came across a confusing sideline in a middle school gym this past season.

The "real" sideline, only the one opposite the benches, was oddly very far away from the bleachers, and players from both teams (and me) thought an intervening parallel line between the "real" sideline and the bleachers was the line for basketball.

Parents sitting there told me, "Happens all the time.".
