Here's the story:
We have been in Yellowstone (we being Justin, myself, and my parents) for the past 6 days. On Wednesday, we hiked up Mount Washburn, a high peak in the middle of park. It is a three mile uphill hike one way, so we planned on hoofing it, with Mom and Dad going at their own pace and returning to the van once they got tired. We lost Dad pretty soon, not because he turned back, but because he found lots of photo opportunities. Mom, however, was determined to keep pace with us, and after much huffing and puffing, the three of us made it to the top.
There is a fire tower at the top of Mt. Washburn, and the public can access two levels of it, one enclosed, and one an open deck. We investigated the tower, and then returned outside to soak in the scenery. Then, shock of all shocks, Dad appears! We assumed that he'd turned back long ago to snooze while we huffed.
Justin connived to get me away from Mom & Dad by saying that he wanted to take pictures from the second deck of the fire tower. From the open deck, we were looking out over all of Yellowstone on a fine clear day, and it seemed like we were on top of the world. He opened up his camera bag, but he pulled out a little velvet box instead of a camera ... and I said yes! Perfect man, perfect place :)
Pretty soon after, we went down to tell Mom & Dad, and Dad took the picture I posted above.
