Sand Canyon, the north side of Little Tujunga. Yes, I remember your story with the rock. The guy I was referring to was Lee, don't know if you know him. He moved to Colorado.

I hit a sharp rock that was hiding in the shade of a bush while descending on Angeles Crest. I heard the tire blow out but I wasn't sure which one it was so I didn't know which brake I could jam on. I wasn't going very fast and I was lucky to get things stopped. Turned out it was both tires. frack
