I'm an avid Pokemon Go player.. I've been informed by other members here that there was no pokestop nor gym at that location, and hte likelihood of there being spawns is low. The event wasn't that great anyway IMO (then again maybe if I'd found a Chansey spawn or two I'd have felt differently), but most importantly - it's very intense and if I try to run Pokemon GO and snapchat both at the same time, pokemon go shuts down and vice versa. Sice we know they were definitely fimlming and posting to snap chat IMO it's unlikely they were playing pokemon go - especially since as far as we know only oe girl had a phone (so only one would be able to play). But it's not really a form of geocaching. You don't go to seek out coordinates and then find real life items or anything. But I won'tget sidetracked on that.
