    "This is a dog friendly neighborhood. Several neighbors have dogs that they walk which is fun to see. We don’t presently have dogs, but we always had one to two dogs with our three kids as they were growing up. Pets definitely are park of a neighborhood community. "

    "I have lived in North Boulder for 30 years- Wonderland Hills and Dakota Ridge, it has always felt safe here. My children attended Boulder Public Schools, I give the schools an A+! We live a convenient short distance to restaurants, grocery stores, schools, and shopping, ...friends hang out at our house and tell me I’m a great baker of Chocolate Chip Cookies! I love to send them home with cookies or fresh dough to bake cookies with their own families! You should bring your kids to our house on Halloween, what a treat! I walk to Pearl Street by way of Foothills Trail, through beautiful neighborhoods apple orchards, Mt. Sanitas and am fascinated by the rock formations. I bicycle many days a week and many miles, such a perfect location to start from and end up! It’s a family and friends tradition to do the Bolder Boulder on the Monday of Memorial Day weekend, so fun! I have been taking it easy for a while due to some physical injuries, but continue to build up my strength and stamina walking my dog, climbing and hiking - I get a great workout! Here’s a tidbit!
