I'll have to agree with the guy above me, especially when you live in a huge city like Houston. It was an opportunity to travel to places where you never thought you'd be going, and learning about various monuments and the history of some of the places. My favorite place to visit would be Hermann Park which is a huge park in downtown Houston. There's a lot of walkspace and a ton of PokeStops. It has become the best place to learn about the great history of the city and the park itself.
