Did you know that the audio cassette tape is actually older technology than the 8-track? It's true! Also true is the fact that cassettes suck, but mix tapes sometimes overcame their medium's flaws.
I spent most of the mid-to-late 80s making regular OC-to-Bay-Area road trips, including a lengthy stretch in which I did that 430-mile drive every weekend to visit a what-the-hell-was-I-thinking long-distance girlfriend. Those trips usually involved packing up the cassette suitcase (remember those?) with a few dozen randomly selected 90-minute tapes, but I also made the occasional mix tape just for a particular drive. For the 1,200 mile road trip I wrapped up last night, I thought it would be fun to dig up the last few tapes from my much-purged cassette collection and play them on the Loneliest Road.
