The 4 way stop was put in after a bunch of my stupid neighbors complained about people going too fast down the hill. I went out for a ride with my "German" son in 2007 and when we came back, they were there. Of course, these are people who yell at DH for going too fast on his bike. The problem is, that it's not a traffic calming strategy when, as with almost all people in Massachusetts, they don't know what to do at a 4 way stop!
It is hard to see over that little rise when you are coming from the direction the dumb woman was heading, but not looking straight! Only if you are trying to see who is approaching from the left.
