I don't feel that way, and I drive it all the time, including today.
Kewl! Guess things have changed! 10 years ago it was a nightmare! But, 40 years ago it was a breeze!
I guess it's all a personal opinion.
I've spent a month in Astoria/Seaside each year for the past few summers and the traffic crawled between those two cities. It seemed to me that the traffic thins out the further south you go. I doubt it has gotten any better over the years (from what you remember), especially with the population growth the northern part of the beach has experienced.
