1. Club lacrosse can play all day in Delaware this summer. 2. However, in Delaware: "Practices, scrimmages, and competitions are allowed in all DIAA-sanctioned sports with the exceptions of football, boys lacrosse, and wrestling." (see link below)
So, if you pay to play lacrosse that generates $$ for state then it is OK. Apparently, no COVID risk. I guess the $$s protects you. If you just play in HS, it is just too risky.
