Cholla has a certain beauty when the morning sunlight hits it, but DON'T be fooled. It is horrible stuff! If you walk near it, the chunks on the ground pop up and attach themselves to your shoe or pants! Don't EVEN think about brushing against it! Nooooooooo!!!!! I took these photos from the safety of my car! I have encountered it many times while walking or hiking, unfortunately. One time a spur got buried in my heavy duty hiking boots and I had to take a pair of plyers to get it off! YIKES!
