Thank you kindly, gentlemen
James, the only cacti we get here in the Northeast are the ones sold in Home Depot as house plants. Indestructible, they say. Until I bring one home, that is
The comedian Demetri Martin made a joke about killing a cactus: "After it died, I thought, Damn! I'm less nurturing than a desert!" I know what he means. So it was nice to see so many of them alive and well, and I hope they still are even after encountering me
Are these Jumping Chollas in the 4th picture?
Years ago I made a visit to the Sonora desert and it was a great trip. We booked a guided tour and the cowboy (our guide) came into the hotel lobby wearing a colt at his hip. Later we had to shoot with this gun at beer cans, a strange tourist attraction. The cacti were impressive, Jumping Collas, huge Saguaros and many others. Beautiful landscape. Thank you very much for the reminiscence.
They could very well be Jumping Chollas, but all I know is that they are prickly little devils, as my shins and fingers quite abruptly discovered.
...And I just checked Google. They are indeed Jumping Chollas and apparently, given the images I saw, I'm not the only one who has experienced them "jumping" into their skin. Luckily I only dealt with one small burr, but it was still not easy to get rid of even that small one.
