We don’t post warnings at the front of our nursery that there might be cactus inside. You know, beware of the cactus, since the name of the nursery is Cactus Jungle, after all. But what about on a desert hiking trail? A letter to the editor of the Carlsbad Patch:

While walking with my family down by the south east end of the Lagoon in Carlsbad Agua Hedionda and my youngest son was attacked by what is known as jumping cactus. Having grown up here in Carlsbad and hiked that whole area since I was young I’ve never seen such a cactus. It was vicious to dislodge from his leg….

I think there should be a warning sign in the area…
