Here’s two reasons to expand the Jack.
One, so we can seat more people for peak games.
Two…
Jack won't be expanded for a long time. A few things have to happen/be decided for it even be discussed:
1. Several more years in a row of attendance like this, note attendance would have been a bit lower if we didn't get perfect weather all year
2. CyTown and other major projects in flight are complete
3. Do they dare get rid of the final 2 hillsides? The next logical expansion would be adding lower level seating on the hills and then adding upper level there as well.
Not to mention we'd likely need some massive donations.
