My mom works at a library that is a gym, doesn't get anywhere near this amount of traffic. Makes sense, and the location isn't big enough to hold that many people on its lawn anyway, but still, kind of interesting to see the difference.
One of her coworkers is trying to make something close by a pokestop. I sent my mom this post and she enjoyed reading it, and it opened her eyes to problems that might happen if they do get a pokestop nearby.
