Honestly a couple things have made the game day experience much worse over the last 20 years.
Excessive media timeouts are obviously not a plus.
And when it's colder out my butt with winter gear is wider than my space allowance.
The advance in television quality and 100-in TVs for $1,000 have made the couch experience better than being at the game in many ways. Especially for older guys like me that need multiple bathroom trips.
Honestly the UW hockey game experience is far better even when they're not winning.
Better seats, more comfortable seats, limited media breaks and contest that are generally around 2 hours.
