Thats interesting. In Northern California, we often start the season (games) with key players missing because they're still in winter sports playoffs. I had no idea that it was so different.
And you guys have better weather!
I believe we can have practice (even now) as long as either 1) its not required practice, or 2) no coach is supervising or 3) no "equipment" is being used. #1 is usually used to start practice, but everyone knows you should be there if you want to be on the good side of the coach.
Are these rules set up by section? Thats the only way I can explain it.
