Last weekend I was in Santa Cruz doing some computer stuff and I went to Costco to get something to eat. Differrent people down there. Lottsa gray hair pony tail types. I liked it.
Not just Santa Cruz. Head north from SF and they get more plentiful the further you go (a few in Marin, more in Sonoma Co., lots in Mendo).
I had one (not grey tho--still waiting to go grey) about ten years back, but as Rod said, it got to be a pain. My hair is fine and straight, and it would just hang there if I didn't have it pulled back. Finally cut it off in 96, and met my wife (who
likes long hair) a month later. Oh well. Timing is everything.
