Ballast Point Park in Tampa, Florida is a hotspot for Pokémon GO activity. Lots of Pokémon to catch, lots of PokéStops to visit. This has brought in a lot of foot traffic, and it seems this rush is causing some trouble for the surrounding neighborhoods. It's also caused an official request to have the park's PokéStops removed.
“We’re consistently responding to complaints about large crowds gathering when the park is closed. The crowds are also affecting traffic, so not only are we dispersing hundreds of people we’re also re-routing traffic to ease congestion in the neighborhood We want people to enjoy the game, but we want them to do it when the park is open." - Tampa police spokeswoman Janelle McGregor
Just last week, there was an incident in the park that ended with a young man being tased by police, all because he wouldn't leave the park after it was closed. No word on Niantic as far as the request goes.
