Just finished a whirlwind trip through Bozeman, Yellowstone and the Tetons. I have just started processing the shots from the trip, but this one from towards the end of my trip stood out from the bunch from a quick scan so did a little work on it in Lightroom and Color Efex Pro 4.
Barn is right on the border of Teton County in Idaho, possibly on highway 32, I was just following my GPS from Jackson WY back to Bozeman and recalled stopping right on the other side of the county line sign.
-- more shots in the Montana, Grand Tetons and Yellowstone albums on my Picasa page (link in sig). Only a handful if that in each album at the moment, but will grow daily as I continue to sort and process through the shots.
