Had the same whilst in Florida 2008 ish, waiting for the ride to set off at the Busch gardens theme park in tampa bay, a lad and his son on the same ride told me they were season tickets holders at home park felt very weird.I don't have a pic, but my son wore his Argyle shirt in Florida recently and as we were walking through one of the Universal theme parks we heard a shout of "Green Army!".
Greens are everywhere!
I must of had 5 or 6 green army shouts as we walked around that day as you say they’re everywhere!
