    "I enjoy the quietness, closeness to nature, friendly neighbors. I appreciate the quality of nearby grocery store with abundance of organic food & quality meat & poultry. Several coffee shops within walking distance. Waldorf Elementary & High School, Foothills Community Park, Wonderland Lake, and City of Boulder Open Space all within a short distance. RTD, the public bus, runs about every 10 minutes from various stops on Broadway. Bus to downtown & to University of Colorado & to Denver International Airport. Northwest Boulder is a fabulous area to live in. My house has continued to increase in value. This area is strong in this economy."
