Sounds like seriously good times!
Most places have shut down their "cruise" for one reason or another. Out here in California, it's difficult to find a town that will allow a car to pass the same place 3 or more times on a Friday night without blue and red lights soon behind it. Most towns have posted "NO Cruising" signs along the major drags.
The town of Modesto is a short trip from me, and it is the town depicted in the movie "American Graffiti". The town was famous for it's cruises every Friday night and was host to the giant "Graffiti Night" once a year celebrating the American car culture and the movie. Today, you cannot cruise in Modesto without being harassed. The city pretty much shut it down with a martial law mentality. Their reasoning was that it brought in too much crime and violence and people got hurt. However, I remember going to Modesto as a younger man and cruising and having the time of my life. It was harmless fun. At the time, I had a hot rodded 74 Chevrolet that was still pretty new at the time. You could pull into a parking lot where other people had their cars and it was like a mini car show. Hoods up, doors open, radios on (almost all on the same station), and everybody was having a blast. If that crowd didn't do it for you, or was not your type, you just moved along to another spot and found a group you liked.
Most of the drive-in type restaurants catered to the cruise scene and had extra staff on hand to cover the increased volume of sales. It was a win-win. I remember Sno White drive in (the BEST burgers, period), A&W for their rootbeer floats, and the mom & pop drive ins along the cruise. The deep fried twinkie isn't new, it was common to find all sorts of deep fried goodies on a cruise night. You got to know the "unpublished menus" of some places by word of mouth, then you went there to check it out. What a blast!!
