Didn't realise how bang up to date this Pokemon Go thing is....it was only released in the UK last week 14th July, the 5th Country in the world after the US, Australia, New Zealand and Germany.
Now if it was more like simple I-Spy, I think i would be good, but the modern Homo sapiens needs a bit more mindless entertainment than that it seems, so these virtual pokemons require catching, and having pokeballs thrown at them.
The game does have its side effects in the real world apparently, and controversy too about accessing sensitive memorial sites as part of the game.
from wiki
National parks across the United States saw an influx of visitors due to the game, with "hundreds or thousands" of people visiting the National Mall and Memorial Parks in Washington, D.C. on the weekend following Pokémon Go's release in the country. Small museums with PokéStops placed at exhibits also reported increased attendance, such as the McNay Art Museum in San Antonio, Texas, and the Morikami Museum and Japanese Gardens in Boca Raton, Florida.
Yes maybe Pokemon Go is insurprisingly not for me either, but I-Spy AA boxes, Viaducts, Bridges of the World, and UK Fingerposts that would be a different kettle of fish.

Wonder if the people at I-Spy have an app for it...
