Flip this Dome!
Get those guys from "Flip This House!" on HGTV to come here and do something with the Metrodome. Actually, it could work.
What if we had a competition where ordinary people could submit a remodeling plan for the Dome. With the Twins leaving, it can now be configured full time for football, no more pull-out seating. In fact, as Andy notes, replace all of that awful seating!
Charge maybe $100-250 per entry, for which you get a full tour, even the heating plant, and the some of existing design drawings to get you started. Winner gets a VIP box and lifetime season tickets.
Why not? The professionals aren't getting anywhere on this.
