My STH rep called me a couple weeks ago asking if I wanted to go out for coffee or something. I declined because I don't live around Chicago anymore.
In any case, they said they were going to start selling tickets to the new stadium after the sale of this season's tickets. I was a little perplexed as I thought they would at least try to sell the tickets for next season before they sell tickets for 2026. So my guess is they are going to do a lot of personal marketing. The rep also made mention of the seat fees, or whatever they call them, will be part of the new stadium, like most other schools.
