My friend Angie came to visit while we were still at the ranch. She'd never been to Yellowstone, so we took a drive down there while she was in town. We were blessed with finding two moose while we drove around! We've seen so few moose, even though we've been in "moose territory" a lot -- it was such a pleasure to see them.
Yellowstone was still mostly closed for the season, so we didn't get to experience any of the geysers. Angie is an avid bird watcher though and there were tons of birds and other wildlife to see.
