Two beautiful cactus landscapes Larry, love the saguaro cactus in the foreground receding into the mountains beyond in your second image—and with the soft lighting. Your first image with the path leading into the scene with the interesting cactus in the foreground is well-placed in the composition.
Jim, love your two cactus landscapes—in the daylight and and night. Love them both! My favorite is the Joshua Tree Park image—love the star trails too. Nicely edited and captured.
There is an issue with Uploading Photos (attachjments). I am not sure what the problem is, and I am looking into it. You can still try to Create your Threads and Upload your Photos, but it is hanging up during the Upload.
