Two years ago. My association starts doing games for a charter school league. "Varsity" games are akin to JV or Frosh games elsewhere (or worse).
Have a girls game, and it turns out one of the teams is from a school and almost all of the players had headscarves, long-sleeved undershirts and pants.
ALMOST! One player had the full-on burqa with a number taped to the back!
This was a real mind-blower and took some time for my partner and I to process. The league was just getting going, and was seeking high-school accreditation. This we knew. Our association knew they would be struggling (getting shot clocks worked in -- a CA thing -- and other issues) The games needed to get done. This we knew.
The scorekeeper from the team was very nice (older sister of one of the players). I had her tell all of the players that they could not have jewelry on, even underneath and play. She said she would make sure. Informed coach that by rule, headgear needed a letter from the state, etc., then we threw the ball up and played the game.
Burqa wearer was and end-of-the-bench sub who played only a few minutes. Team got drubbed badly, but the girls played hard and had fun.
Just a mind-boggling experience.
Had the same team last year, and things had improved. Long-sleeved undershirts now matched color of uniforms!
