There were NO ticks in the Pennsylvania mountains where I roamed. Mom would put a peanut butter sandwich in a bag and I'd walk up the mountain through woods and pastures until the sun was overhead. Which meant that I usually ate my lunch sitting on a rock in the middle of a sheep pasture. I also knew that sun-overhead meant that I had to turn around and hike back down the hill in order to get home in time for dinner.
(I never made it up to the top of that hill.)
I was in second or third grade and we lived in the Poconos of Pennsylvania, and I went to a two-room school one block away.
But nowadays children aren't allowed to roam like that and there are ticks all up and down the east coast and have spread to the rest of the country.
