My mom was a kindergarten teacher in the bay Area in the 70's. I'd tell her that we we're going to the Redwood City Drive In on Wednesday nights, but we were racing her Impala at Fremont Drag-strip (both closed now). We turned the air cleaner upside down to make it sound cool. All we needed was a helmet and a fire extinguisher and we were racing. Man it was slow!
In the 90's I came clean and she was a little pissed but commented "if that's all the trouble your guys got in then I guess I'm over it".
Rest in peace mom
