Lost Valley Ranch: An incredible mountain getaway in Colorado with true cowboy and ranch experiences. Summer 2016, Tate and I worked as wranglers while Brooke worked in the dinning room. It's here where they met and fell in love and have since dated! This summer, Tate and Brooke along with their families came out to Colorado for a family retreat. It was only fitting for Tate to propose at the Ranch.. After breakfast, Tate and Brooke rode their horses up to "Turtle rock" (where I was excitedly hiding)! Tate lead Brooke out onto the rock's lookout point and that's where we dropped his knee and popped the greatest question ever.
