I would wait till the last minute. We have a lot of older fans that attend games, and with the virus, they maybe more willing to set at home this fall, if we have games.
You can always find tickets outside, and normally at face value or below I have been told. Been a long time since I did that, so can't really say it is reality anymore.
Again, they may be harder to get if they put social distancing into the mix. Who knows!
If you make the game, hope you enjoy it, you will get razzed a little, but all is in good fun. The fans will welcome you with open arms, all of us are sure of that.
