Thank you very much Steve. We were there toward the tail end of our trip and didn't want to take a lot of time there, but the park is huge and has a lot to offer.
Happy to see them! I also hope to be there someday, Marc.
Thank you very much Silvia. Yellowstone is very close to the Tetons where you can do a lot of climbing too.
I am looking forward to photos from your latest trip to Morocco.
Thank you very much Marc, i'm working at my pictures, today i've started to select them, but they're so many!
Thanks a bunch Senad. The area is pretty, so it's hard to go wrong.
Superb pics, as always! :-)
Thank you for the kind words Eric.
