Genesee homeowner Teresa O'Brien caught a once-in-a-lifetime moment on video when a huge herd of elk trekked through her yard. O'Brien said her family just moved back to Genesee after living in Jackson Hole for three years and 15 years in Summit County before that. "Great to be back in Colorado and what a welcome by the elk!" she said. O'Brien said her dog can be heard in the background as they watched the flurry of elk running by. "He is still getting used to the activity," she said.
