Right of way people!

In order to "cross the bridge" you must first get to the bridge, correct?

This part is trickier for some than for others.   Unmarked intersections and traffic circles (or "round abouts") apparently push some West Seattle commuters way beyond their capacity to cope -- so they throw their hands up in the air and proceed to wreck things.   

Here is a pop quiz.  When you come to a traffic circle you are supposed to:

a.  Drive over it
b.  Enter it going in a clockwise direction
c.  Enter it going in a counter clockwise direction
d.  Avoid it all together
e.  Speed up and close your eyes
f.   Stop and scratch

If you are confounded by all this traffic circle business, take a looksy here...
