There was this park near my house that my buddy kept trying to get me to go to. I was like "eh, what's the big deal?" at first. I finally went and saw what he was talking about. It was the first place I encountered with like 10-15 pokestops close to each other and there were DOZENS of people walking around in the dark playing pokemon. It was kind of cool knowing that we were all there doing the same thing.
I kept going back, and all of the spots were almost always lured. Just went back on Friday, and it was practically deserted. No lures, barely anyone playing Pokemon. Now my friend doesn't even go there any more. Feels bad, man.
