Hi Len. I live in SW Wyoming, about 3hrs south of Yellowstone Nat'l Park. We try to make at least 5 or 6 trips up there every season. At least half, maybe more, of these images came from the park. That's my favorite place in the world!!!
No Len, I don't. At the moment it's just purely a hobby for me, but I'd like to someday take it a bit further. Some of my images have been published, specifically in Bugle Magazine, to which I refuse any payment and just donate them to the magazine.
I checked out your images too and they're awesome! If you ever find your way out to YNP, let's get together and shoot.
