There is no travel ban to NJ

NJ is not on the quarantine list.

Ny law doesn't control what you do in another state.

There is no meaningful difference between girls field hockey, soccer and lacrosse. The distinction made under NY law is arbitrary.

Outdoor transmission especially above 70 degrees is unlikely.

Stop the madness. The issue is that lacrosse should be allowed in all of NY not that there is one case in a child who will almost certainly be fine and may not have even infected anyone.
