^^ Woah... didn't see the Auburn field after. Did the turf recover, or did it have to be replaced? As I remember, it was warm. Was it June? They also disassembled part of the end zone stadium to get the semis in and out. A LOT of trucks drove on those mats, so they did their job - it just looks like heat stress and lack of sunlight for a week. We did stadiums all over the country - a lot of baseball stadiums as well - you know how crazy baseball grounds crew are about their turf. - wow... I guess this was one of the more southerly venues that was outdoors.
At any rate, any damage to the turf - and repair/replacement would usually be written into the contracts. If the stadium sells, the "trouble" ends up being worth everybody's effort $$$$ on both sides of the ink. The cooler weather is better, and if they get in and out in a few days, that also helps. If this is a one-off stadium show for him, then they will be on the field for a few more days.
