Sorry guys I do not know how to embed the video
From the videographer's description:
"It is hard to realize how many horses there are in a herd of 700, but this should give you an idea! Sombrero brings them right through the town of Maybell CO en route to their spring ranch. I warn you now, it takes 3 minutes for them ALL to come through! This was shot during a part of the annual photography workshop I head that is sponsored by Equine Photographers Network. The footage is unedited, and shot on a Canon 5D."
