  • Daniel F.
    "Neighbors are watching everything that you do and everyone is stuck up. Commute is horrible because of the college students who do not know how to drive a car and everyone is stuck in traffic because of the main roads are few and everyone cuts through the neighborhood. If you like nosey eighties and being stuck in traffic then this is your community"

    "People move here for the historical reputation of good public schools, but that is not the current situation - the schools are rapidly declining in quality. Home break-ins and other crime is on the increase. Too far to comfortably commute to the city. Lots of university students in this neighborhood means it tends to be loud on weekends and Gnarled Hollow is like a racetrack."
