Funny enough, Phish was going to have this at their 2018 festival “Curveball” (cancelled due to intense rains, flooding, and sewage problems in western NY where the festival was taking place). The drummer (Fish) talked about this at some point, I think on a podcast… anyway, they were going to have a shortcut back to the tent camping area but it would have crossed a “mime field”, where dozens of paid mimes would be messing with all the phans coming down off their highs on the way back from the show each night.
