Thanks Anya...how common? Really caught my attention. Edible? We bought some cacti at Wholefoods before we returned home....we always enjoy it in restaurants, rarely get a chance to fix it at home. Cheers.
Ha, ha, I'm so used to having cactus spines in my body after hiking in the desert that sometimes I don't find individual spines until a few days later. But one day I tripped below Moapa Peak, fell full force and "impaled" one of my hands into a red barrel cactus. That was something else! It took a few days before I could move my fingers again.
""You cannot stay on the summit forever; you have to come down again. So why bother in the first place? Just this: What is above knows what is below, but what is below does not know what is above. One climbs, one sees. One descends, one sees no longer, but one has seen. There is an art of conducting oneself in the lower regions by the memory of what one saw higher up. When one can no longer see, one can at least still know.""
