Seattle is in a tie for 7th so you know its a tuff place
to pass through or just get from the north into
Seattle or just getting from the south of Seattle or
just getting in from the east of Seattle. Then reverse
getting home in the PM. Seattle traffic includes conjestion
from the Canadian Border south to Centrailia and we are
talking "I-5" as the big funnel to all this constipation.
I-405 which runs runs through the east side of Seattle
through "Hellview" and meets up again right around Sea-Tac.
Most cities to the north-south-east of Seattle are in grid-
lock traffic every am/pm. Right now Everett is keeping pace
with Tacoma with some of the most serious traffic problems.

If you are in a horror movie, you make bad decisions, its what you do.
