Mojave and Joshua trees

We left San Diego at 1:00 pm yesterday and drove to Mojave last night. With sunset just after 5:00 we miss lots but we had a chance to see the strange but wonderful Joshua trees that are a sign that you are in the Mojave Desert. They appear suddenly and disappear just as fast. I can't remember if it is latitude or altitude or a combination that they need but these Dr. Seuss trees are hard not to love. Well for tourists anyway. They only show up in parks or in deserted properties. No sign of them in "well-cared for" gardens. I think they deserve respect when you realize how slow-growing they are. We saw a couple that must be 100 years old.
I'm taking pictures by hanging out of the truck as we whiz by so you either get the tree coming or going! We are home-bound and not taking time for pictures.
