The USWO practice rounds were closed to the public on Monday this year.
As soon as you let the public in, you're obligated to provide parking, shuttle services, first aid, disability services, security etc etc etc. Even by Wednesday the volunteers still outnumbered the spectators 2-1.
Kudos to the USGA and Fox for so much coverage of the various events. Curtis Cup at Quaker was good TV despite the blowout, and I'm sure next week will be the same.
