About the owner:
I'm a geo-physicist by degree, a design development engineer by trade and a mountaineer by choice...
I live in very, very rural Oklahoma and worked for a Norwegian company. And a Chicago company... and a Salt Lake company... And now... well, I just do work for whowever I feel like dealing with.
and I climb mountains, mainly in the western hemisphere. Occasionally, I go to Patagonia in South America to climb.
I like my ATV rides out in the country to photograph things... all over western Oklahoma roads. Dirt roads only., thanks...
I do "projects"; around our place, building things and creating mechanical devices. So a lot of my photos revolve around my workshops (I have 4) and the things I build... + our cats.
Whatever..... I'm having fun.
