    "I work in Berthod Colorado, which is a thirty minute commute. The views are stunning. So much of the great outdoors are preserved here. It’s truly magical. At the same time, there is a bus stop right next to my house that would be handy if I worked in town in Boulder. "

    "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!
