I hear a duh-da duh-da duh-da duh-da towards the end of the video. Sounds like a Chickadee scolding (I think) but I don't know if that's what you're referring to.
Oh nice!
It's about 4 hours from the Utah/Wyoming border to the South Hills. It's a long jaunt but it's worth it! You could stop at Antelope Island State Park as well. Are you camping along the way or staying at hotels?
