In my area, we had a huge swimming pool complex that had been built into the side of an old rock quarry. Virtually everyone went there on weekends, as it was one of the few public pools around in those days. They had the big main pool, baby pools, a games area and a dance floor, and they always played the current popular songs for our "dancing pleasure". And dance we did; as the sun burned brightly and tanning or swimming became boring, we piled onto the dance floor like sardines in a can. It was heaven. If your current boyfriend was not in attendance that weekend, there were always scores of others waiting in the wings. And don't get me started about life guards; they of the bronzed bodies and rippling biceps. It was every 15 year old's dream, even if the guards were far too old for us.
During the week, my girlfriend and I would walk about a mile every day to the local dairy store to have a Coke and an order of fries. We told our mothers that the reason for this daily foray was our friendship, but we were not completely truthful. The route we walked was guaranteed to take us by the homes of some boys whose attention we coveted, and some days we were rewarded with a wave and a hello or maybe conversation, if we were very lucky. I don't know if they ever realized our motives, but we were so obvious I don't know how they couldn't have.
Summers in later years were not as idyllic, since I had to work and save money for college. Those were good experiences too, of course, but the best summers were spent in nature, sitting on a rock or turning it over to see what was underneath.
