Measure of a cactus

We stayed with cousin Elise and Carl at their house at Dove Mountain. It is a well planned development with natural areas preserved among the homes. I like the idea of mixing humans and nature. It is good for the human soul & allows for the sustainable preservation of nature when done correctly. The pictures are from the natural areas near their house.
You see my picture with the cactus. Carl saw my picture with my pine trees and liked the idea of the comparison. I have become a unit of measurement. This saguaro looks to be about five matels high.
