Like Bricker, Spoke, and a few others, my high school years straddled the 70s and 80s – 78-79 to 81-82. Disco was definitely a junior high phenomenon for me. By early high school I’d moved on to 60s rock and early 70s heavy metal, and by the middle of my sophomore year I’d pretty much thrown that over for punk/new wave and various other more eclectic tastes (I became a big Lambert, Hendricks, and Ross fan at about this time, for example). I even overcame my disco/dance music aversion enough to enjoy Kid Creole and the Coconuts. On high school band trips, I frequently found myself in boombox duels with the Loverboy/Styx/Lynyrd Skynyrd contingent, countering with everything from the Clash and Sex Pistols to early Squeeze to the Modern Lovers (the Walkman was introduced while I was in HS, and was too expensive for me for the first couple of years, and besides, inflicting your tastes on others was part of the point).
Apparel: what about pitching-sleeve shirts (long sleeve t-shirts with a solid white (usually) body and colored sleeves; running shoes even among those of us who rarely ran except to chase down an errant Frisbee toss. I was as likely as not to be wearing a Clash t-shirt with my Dad’s early 60s vintage Army fatigue jacket over it, occasionally topped by a plaid scarf in winter, or flannel shirts; my senior year we moved to a new town, a small farm town in the Delta, where I took to wearing a gray herringbone tweed sport coat, white dress shirt, and narrow solid color knit ties, with various band and record label buttons on the coat – anything to further mess with the heads of the other kids and teachers there. Among the things I didn’t wear that I saw all around me: down vests (particularly orange ones in the deer-hunting areas I lived in), wide-wale corduroys, Jordache jeans, etc.
I suppose the Trans Am and Firebird were the characteristic vehicles of the age, but the Chevy Monte Carlo/Buick Regal/Olds Cutlass and whatever the Pontiac equivalent was were pretty much the thing as well in Fayetteville, Arkansas at the time. For some reason, however, the parentally owned and maintained Dodge Dart was the most common vehicle in my set; had the misfortune of having to drive a '75 Dart myself through most of my high school years, until I finally rebelled, learned to drive a stick, and assumed my dad’s old '74 Datsun B210 hatchback, which served me well throughout my college days.
Midnight movies: living in a college town, the local theaters had a habit of playing things like Rocky Horror or that godawful Pink Floyd movie with all the bubbling mud flats or The Last Waltz at midnight on Friday and Saturday nights.
Better living through chemistry: gobbling the old formula of Primatene tablets as a cheaper, legal, OTC alternative to speed (Hunter S. Thompson was my idea of a role model at the time).
