It took me fifteen minutes to track it down, and we almost drove Nico's poor dog crazy as we lead him back and forth, but I caught a tauros this afternoon. I was so afraid that he was going to despawn by the time I got to him, and I wound up using almost all of my pokeballs. I still think he was worth it.
I wonder, when the next generation comes out, will we get another region specific pokemon, or will it just be the places that got left out last time? Should I hoard tauros to trade?
Also I don't think I've ever played a video game that's made me walk so much before.
