Do you reckon high schools would 1. keep copies of year books from decades ago and 2. send them out to former students? I've been thinking about my high school years and don't remember a whole lot about it. I don't have the year books anymore and would be nice to take a trip down memory lane. I figure there might be privacy concerns or whatever, but thought it might be worth contacting my old high school and seeing.
But the river by the school has flooded many times since the 80's. Odds are the cave paintings have been severely water damaged - if not washed away entirely in that time.
