    "Even though people are good about picking up their dogs’ poo, not everyone is a responsible dog owner. I rarely ever see any leash-less dogs. However, some people claim their dogs are service dogs when they’re out of control. Most places here do not like big dogs in the complexes. "

    "This is an absolute amazing neighborhood! It is not the type where your neighbors stay inside all day and never come out, or the type who are always nosy. It is perfect! At night there is no parties going on until like 3:00 or anything! It is quiet and nice, in the morning the birds are tweeting and you see people walking their dogs, biking, or just jogging! I totally recommend this neighborhood!"
