Great Horn music!
That’s the one they filmed with a small model drone (helicopter). It is cool.
A video equipped quadcopter is on my wish list

Awesome. Can’t wait to get back there. My guess is we will be doing a Colorado trip next summer as Matt & Alyse just announced they are expecting their first. in very early spring.
Beautiful video with stirring music. Thanks for posting it.
