We had a very irascible gym teacher who, I’m hoping, would not be allowed to work with children in this day and age. She made us line dance to “Peg” and “Hey Nineteen,” which itself wasn’t so bad, but just one more thing that I associated with her. As a result it was many years before I could tolerate (much less enjoy) the music of Steely Dan.
Not sure; there may have been. Within a few blocks there was also a health food store (which in hindsight seemed very out-of-place in Arlington) and a fast-food joint called Burger Box – their logo was a styrofoam clamshell container; ironic because those started to fall out of favor a few years later.
The Taco Bueno’s still there and looks the same as it always did. (Burger Box is still down the street, too, but without the styrofoam clamshell logo.) ETA: At the time you lived there, So. Cooper was under constant construction and your parents probably grew aggravated with any errand involving that route.
