If we didn't go swimming, there was a 40 acre woods/orchard behind our houses and we would search it for anything exciting, like bugs, squirrels or wild animals.
When I turned 8 we moved out into the country and I had to walk a few miles just to get to a friends house. We'd usually take our air rifles and go try to shoot things. By the time I was 10 most of us had our own motorcycles and parents who would let us borrow their shotguns for some real fun.
This was in the 1970s.
