Sheese...the midweek games in Feb./March, the place is only 5% full usually anyway. They should let those faithful few in...there is ample room for social distancing...
In lieu of regular ticket sales, I'd just put, say, 100 stadium passes for each game first come first served to Season ticket holders, then WPC members, then the public. Use the existing ticket transfer software to allow games to be "claimed" by folks who can and want to show up. distribute another 50 to students on the hill.
To extent folks still mingle on concourse, however, system still has strong potential to become a superspreader...you can't force everyone to remain in their seats at a baseball game, because it's almost three hours typically... And of course there's the problem of the yahoos who believe COVID is a hoax and refuse to wear masks...
A foolish consistency is the hobgoblin of little minds.
