When I was 10-years old and had a single ticket, while mom and dad had their own tickets elsewhere --- they said, "Meet us under the water tower after the game."
At the end of the game with about 55,000 in attendance in the 1960s, I didn't know how I could find the water tower after the game, much less find my parents there after the game. But, that tower loomed over the stadium. It was surprisingly easy for a 4th grader to reunite with parents under the water tower. I wonder how many other kids heard their parents say that. It worked every time. I loved that water tower.
