Sarrah Countdown #14

Sarrah on my uncle's mountain.

We found these horses in a pen just north of Livingston, Mont.

On the shore of Yellowstone Lake, Sarrah collected stones to write "I love you" for a photo for her boyfriend in Arizona, Dylan Jung. She later used the photo in a shadowbox for him.

Sarrah Countdown #12

Roosevelt Arch, the main entrance to Yellowstone National Park. It used to be the only entrance to the park, and lies on the Montana side of the border. It's eight miles from my aunt and uncle's ranch in Paradise Valley.

Just inside the park, still in Montana before we reached Mammoth Hot Springs.

Sarrah was leaning over the edge of this cliff to snap a few photos. The wind was fierce, maybe 30-40 mph.

Sarrah really wanted to see this buffalo up close, so she wandered out to see it. Then it charged the truck. It really just wanted to cross the road and ran right in front of us to the other side.

On the shore of Yellowstone Lake, Sarrah put sunscreen on me. I was already burned by this point.

Sarrah Countdown #10

As she made her first steps into Montana, Sarrah and I got out of the truck, wandered into the median and shot photos of each other.

One of the best parts of the trip was spending a full day inside Yellowstone National Park. Buffalo were scattered across this valley.
