We went 3 or 4 years ago. It wasn’t shoulder-to-shoulder – not like 4th of July – BUT you won’t get parking unless you go very very early, so have someone drop you off, or ride a bike, or walk … Two years ago I got stuck in traffic on Alki SW right at midnight. Oy.
Enjoy the fireworks wherever you are. Myself at this point in my life I’ll sit in my nice warm apartment and watch it on TV. Have a Happy New Year. I’m not chicken, the arthritis in my feet doesn’t like cold for long.
