As happened to me. My house is located approximately 50 meters from Pokemon GO Gym. As a player Pokemon GO You do not need to tired to walk far to hunt Pokemon if Your home is close to Pokemon GO Gym. Because, it seems the gaming system automatically spreads the Pokemon around near the Pokemon GO Gym.
And be prepared to meet Pokemon :

Appeared again in front of the TV.
