In 1972, on my second cross-country motorcycle trip (this one with my then gal-friend), we were planning on staying overnight at a campground near Newhall, CA before reaching LA. We couldn't locate the supposed campground and when we stopped for gas at a Shell station there the owner offered us use of a station wagon behind the building as a place to sleep overnight. So that's where we spent the night.
Next day we toured Universal Studios. On the way in to see live broadcast of Robert Q. Lewis radio broadcast they asked each audience member to write on an index card the most unusual thing that happened recently. Of course I wrote that we spent the previous night in an old car. Needless to say I was called up to the microphone to tell my story which I nervously managed to get out without fumbling too badly.
