There is quite a bit of it growing in the backcountry around Big Bear (So Cal), but you'll only find it in a rather narrow elevation band. I inquired at the ranger station about getting some for a woodworking project I had in mind and they told me I could get a permit to collect some, but that was a ... few ... years ago. Some was also in areas open to firewood cutting, and permit for that was $15/cord, but only for dead material. The thin red bark usually peels off if the bush dies and dries out, but then I gues you'd call it manzana podrido
. And yes, you can ride your motorcycle out there, so its not of-topic!
