You sir are an inspiration!!
My wife and I opened a restaurant last year so our limited vacation time has all been spent with family. I am itching for some time outdoors real bad!! Keep up the good work so we can all live vicariously through your beautiful images. If you ever have any questions about workflow and keeping it light shoot me an email! What are you using to edit?
