Still have to find a billboard company in the city that would actually sell them the advertising space (which they probably won’t unless they find a company that’s in a dire financial situation due to the pandemic).
I think it was the falcons who tried to pull this stunt a few years ago, and I remember the billboard companies saying they had businesses call and threaten to pull all advertising with them if they put up the falcons billboard. Wouldn't be surprised if it is the same situation here.
