On the DLS sports site they posted a notice from SM (Stockton) that tickets would be available at the gate but they're recommending to buy both JV and Varsity games in advance.
Saw earlier elsewhere on this site that tickets for the Pitt-Serra clash would only be available to players family members.. But did not find any confirmatiom of restrictions yet
Might be good to start a thread for restricted and non-restricted attendance policies to which those who know can share.
Health/safety guidance In San Mateo County indicates that, at least this week, fans will be allowed at all outdoor prep athletic contests. Will be wise to monitor the situation on a weekly basis. Coaches (and others) have their fingers crossed.
