Some sounds I remember:
The ice cream truck’s bells coming up the neighborhood.
Using a clothespin to anchor a playing card to your bike’s wheel to make that cool whirling noise.
Using caps guns with the paper tape with gunpowder on it to make real bang sounds.
Setting on the front steps eating watermelon, while seeing who could spit seeds the farthest and loudest.
The roaring whoosh from the grill when you Dad lit half a can of lighter fluid to get the charcoal going.
The sound from those bulky, tinny drive-in movie speakers your parents would hang on the car window.
The noise big four engine propeller driven airplanes made.
