    "People walk their dogs here. It seems like a fine place to walk. It’s also important to be wary of the wildlife. The dog often gets excited to chase deer in the neighborhood. "

    "Great mix of folks. Fabulous location; close to Boulder and Longmont, 22 miles to Estes Park. Great access to mountains but many close parks and trails too in Hall, Heil, Rabbit Mtn, and the Longmont Dam/Price Reservoir. "

    "I live in this area and it is sometimes shocking how beautiful and serene it is. Surrounded by national forests and trails, you can find stunning rock outcroppings, smooth rock rivers and fields of wild flowers. The community is respectful of privacy but extremely helpful if needed-- as witnessed in the floods. Lyons is a close 10 miles away with a vibrant art and music community and delicious restaurants. Estes park is about 15 minutes away, which is where Rocky Mountain National Park is. There is a ton of wildlife too. Definitely a slice of heaven. "

    "This is a friendly, spacious and laid back area two miles outside Lyons town limits, with large lots and privacy, yet only a half an hour from Boulder, and twenty-five minutes to Longmont."

    "Ride 20 or more miles of amazing singletrack and then hit Oskar Blues for great food and beer (and maybe a show). Or just hang by the river and read a book while tubers float by. Plenty to do in Lyons, lots of friendly folks, and a mellow atmosphere make it a great place to live. "
