They returned to natural grass, and they just expanded and upgraded WIFI access for fans during games. I can't recall exactly, but I think when Louisville switched to field turf, it was partly due to drainage issues when the surface was all grass. If that remains the case, then field turf it is, but, given there's a developing link to those little black pellets and cancer, perhaps a reevaluation of player safety is needed. I'd be all for a return to natural grass, if it could be done. Additionally, it's quite archaic sitting in a "state of the art" facility and to be unable to send and receive texts, or check for scores, weather updates, etc. on my phone. There's a part of me that thinks Tyra has mentioned this at some point, but I'm not sure.
