GRASS LOTS PARKING ???????

I am not sure where my wife and I will be parking for games until the day before or day of due to some scheduling (my son has soccer games on a lot of the Saturdays). Is it hard to get parking passes at the lot when you pull up?
According to the parking pass sale info site (listed above and here ) I'd guess it will be nearly impossible or at least very unlikely.
"Pre-sale parking will be sold online only and will cease at Noon the Friday before each game OR when passes sell out. Pre-sold parking passes for public parking lots allow entry into one of the public parking lots, all will be first-come, first-served with pass holders choosing their lot upon arrival. If available, parking passes for the general public lots will be available on site the day of the game."
 
If you are worried about parking in a GA lot just get your pass now then if you can't make a game they are digital passes now so I'm sure once they sell out there will be some resale demand for them you will be able to transfer it. Especially the games that you assume now will be well attended I would not chance it.
 
I'm just wondering why a Hawk fan started a thread wanting to park in our grass lots......?????? :)
