A herd of bison in the Hayden Valley region of Yellowstone National Park.
Thanks a lot to everyone who commented on my photos, or even stopped by for a visit. The comments have been pouring in pretty fast and I'm finding it increasingly difficult to reply to each individually. I'd rather spend that time in viewing others' photos and commenting there. But I do read each comment individually, and if you ask me something specific, I'll answer that.
