"Pleasant street running through Pinehurst connecting Lake City to Northgate"
This is a nice and quiet residential street in Pinehurst neighborhood in Seattle, where you'll find plenty of families. It's OK for walking, although it has no sidewalks, and since it cuts through Pinehurst parallel with 125th Ave NE, it can get busy with cars. Larger hills sometimes means speeding cars, although I don't feel unsafe walking with my children on it. I would be less likely to let them walk alone. Overall it's pretty quiet considering it's proximity to the Northgate Mall and Lake City Way.
