The stadiums built in the late 1960's onward did not have troughs. And many stadiums just before that did not have them. The seats were plastic. I know by every way that modern stadiums are better with massive technology ugrades. There are people though who do not like the loud noises from the sound systems and the constant selling of products on the ribbon boards and the large jumbotrons. Free parking to very low cost parking as compared to 20 dollars at baseball games and 30 dollars and more at football games is brutal.Want to talk old time stadiums?
Announcer just gave down and distance, old stadiums had bad echoes and bad sight lines. Most stadiums doubled as baseball stadiums and in the fall, you played over the baseball infield.
Those turf fields were torn up by mid season and mud and slop when it rained.
No Jumbotron replays of the action on the field
The food sucked but the beer was cheap
Aluminum seats in the winter and trough urinals were not so great.
I remember seeing those troughs when I was a kid......freaked me out
