I walked downtown for about an hour and didn't see anybody (even kids) shooting water pistols
Yes, urban kids prefer to stay at home with their smartphones. In the countryside it isn`t better. Sad.
I've seen plenty of buckets of water chucked over the years
That seems to be the song of the past now. Partly due to cities closing down street water pumps. When I was a child, there were two public water pumps on the way to school. We drank from them on hot days.
