Dear NG experts,
I will be in the USA in Washington for a workshop starting 16 Oct to 20 Oct. Thereafter I have a week additional in the USA with my wife Marie before I have to fly back to South Africa. I would love to visit Yellowstone and/or Yosemite during that week. Advice would be welcome, especially an organization or individual that can arrange a tour with a focus on photography. I am not keen to drive on my own for a variety of reasons.
Kind regards and thanks, Martin
