You can almost picture the cows just on the other side of that hill. But this isn't Vermont - it's Milton, down at the Neponset River, across from Pope John Paul II Park in Dorchester. About 300 feet to the left of the houses are three radio towers - and next to those sit a couple of office buildings (in Quincy). But that's one of the cool things about the park: Sure, you can look one way and see the Southeast Expressway, and turn around and see the Red Line, but then you turn again and see views like this.
