I have written to Dan a couple of times in the past asking if we can add his photos to the ATP database and maybe my emails went into his spam folders, never heard back from him. If anyone is in contact with him, perhaps they can ask? And let him know we add links back to his site with every image.
I have always loved his real life in-the-garden images! Used to chat with him on the phone a few times when I was the procurement chair for our club, he is a character!
