    "My commute to work is straight down Rt 9. Ten minutes, if that. I live here out of convenience. Neighborhood is college students on all sides. Not the most desirable neighbors. "

    "A quiet, private location great for kids and pets, and parents who want their kids to go out and play. Abuts (9th?) fairway and hole of Hickory Ridge CC (XC skiing out your back door). Look for wild chives, turtles, muskrats and garter snakes along banks of Plum Brook, which winds through north section of property. Most of soil on property has high clay content. Originally had (perhaps still has?) a working fireplace in the half-cellar (an underground spring precluded a full cellar). Lots of space in attic. Hallway in the bedroom 'wing' was long and wide - perfect for games like Mother-May-I, RedLight/ GreenLight, and Walk the Walls. Short walk to Mission Cantina, Moan & Dove, PVTA stop, gym, and Pre-through-6 schools. A snowplow, chainsaw and ride-on lawnmower are highly recommended. "
