OK. I'll play along. November 10, 2019 is plausible for a stadium announcement. So is any date between tomorrow and 10 years from now, but fine.November 10, 2019 - Save the date.
October 10, 2021 - Save the date.
But what could possibly happen on October 10, 2021 even if we announce in the next few weeks? It's too soon to open, and why would you open in October anyway? I sure hope we don't break ground 2 years after announcing.
