This came out earlier this month. My daughter was the first to download it. As a result she outpaced my son and I on catching pokemon. We discovered quickly that (assuming you are the passenger) you can catch pokemon as you drive down the street. That meant I couldn't keep up. So, just to see what would happen, I put out an incense and sat while watching TV. I had a pidgey, a zubat, and a spearow show up. Too bad my cat didn't notice.
This one was outside of the house. Be careful of pokemon in the street. Not a good idea to wander out to catch them in traffic (even on a quiet neighborhood street).
