I was up at the local overlook with my camera and 500mm mirror lens on a tripod, setting up a shot of the mountain in the distance. A couple of young guys were sitting in a vehicle slightly off to side. As I get ready to take the shot, I hear in a perfect SoCal dude accent, "Hey don't take my picture, duuude!" I assured him I wasn't and told him he was nowhere near being in the image. He replied, "Awright dude, cool."
Later I reflected on how little the speech of a significant subset of local youth has changed in the last 35 years or so.
