Sylmar Hang Gliding Association

did anyone photograph it? it wasn't this amazing, but it was identifiable!
there was a huge cu-nim w/ anvil that kind of got lenticulated, then it looked like whip cream being stirred, and less than a minute later, 3 sections of it had gone mammatus. (my first one! alas, forgot a camera...)
