So the company that made it, had a flag ship game called ingress. The poke stops were places from the first game. Granted it didn't catch on as large as pokemon. It let's you submit places of significant for historic, cultural, artistic significance. The reason merrily feild was added was probably because of all the charter companies that do tourism flights out of there. It's not the makers fault they are there. Notice how the last 4 years ingress has been arround, you never heard of these problems. Pokemon is very user friendly towards all ages, and has only been out a week and is causing issues because a lot of the youth that plays doesn't exercise common sense.
