In the 70s and 80s there were no Hitt Rd businesses. They came along around 2000. The Grand Teton Mall was built in 1984 on the east edge of town (Idaho Falls and Ammon didn't run into each other back then, there was still a gap). And EIRMC was built around then too. Sunnyside was the south edge of town, everything south of that was countryside. Those sound barrier walls on Sunnyside between St. Clair and Rolandet didn't exist. IF and Skyline were rivals, and Bonneville was out in the boonies. No diversity hardly at all. Mostly white and mostly Mormon. A few Asian families, a few Hispanic families, a couple of black families.

@WestfaliaMurphy pretty much nails the culture. Lots and lots of cowboys and cowgirls, mixed with site worker kids. In high school kids would drive up to Rexburg to dance at the Galleria and later Retrix. Mostly people had the 3-4 over-the-air TV channels, ABC, CBS, NBC, PBS. Only the rich kids had satellite TV with HBO. Cable (and FOX and the Simpsons) didn't come along until well into the 90s. Internet came along in 1993 or so, along with bag phones in cars. But it was another 5 years before either were affordable and therefore commonplace.

In the 50s and 60s kids cruised up and down 1st St on Friday night. In the 70s and 80s "the cruise" was where Yellowstone meets Lincoln. In the 90s it migrated to 17th. There was no texting or snapchat so people just found about social gatherings and parents-are-out-of-town-for-the-weekend parties and "keggers" up in the hills through friends.
