Here are a few streets that I like due to the fact that they are up on the hill (good view potential) and far enough away from the 5 and 8 fwys to not have much car noise:
Illion St. (section North of St. Mary Magdalene)
Harford St. (South of Milton St.)
Streets that branch off of Milton St.:
Tokalon St.
Garfield Rd.
Cecelia Terrace
Dunhaven St.
Penrose St.
Southcrest Ave.
Fairfield St.
February St.
March St.
August St.
September St.
That whole plateau is pretty nice and quiet. The reason I mention that the above streets branch off of Milton is because they continue North of the canyon where they end (North of Western Hills Park) and are not as ideal — nothing bad, just not as good as the streets that branch off Milton.
