In addition to a tour of their greenhouse, we had a walking tour of the local area. It is amazing what you can learn to see with a good guide. Knowing what to look for is always the trick, and there was no exception even in the semi-desert environment. The variety of cacti and learning to spot the young cacti as they are barely above ground was eye-opening. The final thing that I can say is something that I try to adhere to but that was driven home on this hike: Stay On The Path! Don’t go trampling if you can help it. You are stepping on baby cacti.
