    "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."

Our schools excel in S.T.E.M. studies and the children here are going to cure A.I.D.S. and cancer someday. Very quiet and family oriented area. No troublemakers here.
