I dumped most of mine in 1960 when they were cheaper. I kicked myself in the ass in 1970 when I saw the sudden rise... Ahh.. the bull market back then. Those were the days when I was taking the kids out to Disneyland on one day's worth of trading 
I know the feeling, in the 70's I was trading Bison, I had no idea Yaks were the one to be in.
