Went for the Thursday line up and it was great. Was initially skeptical but the set up works well. The GA lawn area in front of the stage handled all of the crowd and had room for more. No idea how many were there? Could have been 5k or 10k IDK.
Plenty of food drink options near the stage. If you want to sit down just walk across track, which was kinda cool actually, and it's open seating in the bleachers which are metal but do have backs and a like a knee level metal table running at the front of each row.
The concourse behind the 1st level bleachers has various vendors and a couple of nice long wooden
Bars with stools. Even an Allsups convenience store.
Sound was perfectly good whether up top on the concourse, in the bleachers, or if you want louder down in front of the stage.
The nice weather contributed but I have to think the best part is a facility that could hold maybe 100 or 150k being used for 10-30k or so means nothing is stressed. Plenty of parking, easy to move around, no lines. At least that is the Thursday experience and may be change a little with bigger crowds.
