We also used to go to little league games on our own on our bicycles, and play without our parents watching (thank God!).
A couple of times, a friend of mine and I in 4th grade biked the 8 miles to our school outside the city in Miquon.
At age 13, my dad gave us the run of the city and the surrounding area (Philadelphia), at least as far as our bike or the bus or trolley would take us, with the main rule being come home for dinner at 6. So now I could bike 6 miles to the hobby shop in Jenkintown on my own, including biking on suburban roads with no shoulder or sidewalk and biking down the side of the 4 lane divided highway (oh the horrors!).
When we really wanted to have fun, my dad took us around to places we otherwise could not get into, like climbing up the huge abandoned cranes at the defunct Girard Point grain terminal in S. Philly to catch the views.
Dad (who was a chemist) also brought home the necessary chemicals when we wanted to make gunpowder, and beakers of liquid nitrogen for "experiments" on our insect compatriots.
This was 1977-1990. My wife can't believe the freedom I had. Like running down to the next block on my own at age 3 1/2 to go visit my best friend.
"Man, I wish I still had those cars, they would be collector items now", he told me. I asked him what happened to them, and he said "we built roads and tunnels in the dirt and blew them up with firecrackers!!" LOL!!
