Downloaded the app today with a friend and we drove around in my car around the center of my county. Churches and post offices seem to be frequent pokestops. We did a drive-by pokestop as we went past a park. I hit the brakes in front of the park, he spun and tapped out the window, and we sped off in front of a bunch of people swimming in a river. Also attracted the suspicion of a cop who saw us stopped on the side of a highway in front of an eyecare building in my unmarked police car. He hit his brakes but didn't stop nearly in time to do anything about it. I gave him a look and took off in the opposite direction.
Here's a good way to get a bunch of Pokéstops! Go to your local zoo! My zoo had so many Pokéstops!
Yeah my friend has a friend who confirmed this.
