He means that the Inside-Kinnick experience has deteriorated about 1400% since Dad first worked in Iowa City. The University, the IC folks, the "neighbors" around Kinnick, the UI Hospitals, etc., have turned it into one of those new-era-Trick-or-Treat deals where nobody wears a scary costume and each kid gets EXACTLY the same number of pieces of candy. No longer full-sized candy bars, just small mini's or individually-wrapped mini-bars. Alcohol not "illegal", but certainly "discouraged". A-hole fans who complain to the security when a rabid fan stands up for longer than 3 consecutive plays because the Hawks are moving the ball on the type of drives we had to open the O$U and NW games.
Pretty sure that's what he means. That, and he heard OK4P might not be at the game, thus dwindling the joy for everyone in attendance.
