I grew up in a town with a wealthy area. (not where I lived). We used to “camp out” in our yards in the summer and about 1 or 2 in the morning go to the wealthy homes and jump in their built in pools. There could be as many as 20 boys.
When I got to college I found out other kids in other areas with wealthy families used to do the same thing.
One kid always told the story of growing up in Montclair and swimming in the backyard pool of the family that owned Swanson Foods. Problem was he and his friends were uninvited guests between midnight and 4am.
