Across the street from where I live there is a foot bridge to a park I have never gone to in the 20 years I have lived here. Last night I went over there due to the huge amount of pokestops and the gym. I discovered there is a snack bar there that is open to 1:00 in the morning and I bought snacks and managed to catch a high level Arcanine.
There was a crowd of people there catching Pokemon.
