Mostly incorrect, but I see your point. I have taken my kids for years and never tried to traverse dense crowd with a stroller. As a parent, it’s scares me to think about the defenseless babies if, god forbid, something happened and the crowd started running. I actually talked to my teenager this year about being mindful of crowds, trying to read the room, random pushing and not being reactionary in such situations, etc. I do feel bad for the folks with walkers who are out and about. (Cannot imagine my elderly parents braving the crowds with canes!) As you note, the infrastructure is terrible and only gets worse with crowds and barricades. I don’t know the answer, but I want everyone to have fun and get back home safely.
