    "I have lived here for 19 years. The community has a small town feel at times and at sporting events for the local high school. But the shopping is difficult if you want a nearby grocery store that has traditional American staples."

    "There are a lot of dogs that bark at our dogs when we take ours for a walk. Sometimes owners don’t have their dogs on leashes, either. It is a dog friendly neighborhood though, and I like that. Sometimes there are a lot of people walking their dogs around the neighborhood. Our dogs protect our home so I am glad they are accepted here. Also, many people bring their dogs to community events."
