I was at Monster Jam two weeks ago, tomorrow and I filled out the survey they sent too. One of the questions was, "What can we do better?". To which I left a one word answer: Venue.
Even in the 200s the rows are too close together. The only way I got rid of the cricks in my knees (I'm 5' 8-1/2" on a good day) was to straighten them on the drive home and drive with my toes.
Less than a week later, my family sat in Row H of the lower bowl for the Globetrotters. The rows were there are as close as above the concourse, only I didn't only have a 7 year old in tow. The father in the other family is 6'-4". We concluded that at least one seat in every row should be removed, with wider seats installed, but at the end of the day there is no inexpensive solution to put more room between rows.
About 24 hours later, I brought my 7 year old back to the XL Center for the Memphis game. I wrote about it in a different thread, but let's just concede that the arena and it's amenities are not built for 16,000 people as they exist in 2020. I was born in 1977, so I don't know for sure, but dare I say that it wasn't built for 16,000 people in 1970 either.
