11:55 AM: Alki’s biggest post-holidays winter event is happening now – the Special Olympics of Washington Polar Plunge. The “plunging” doesn’t actually start until 1 pm, but the accompanying food-trucks-and-beer festival is happening now:

We counted 11 trucks – from west to east, Off the Rez, Thai-U-Up, Tabassum, Kathmandu MoMoCha, Whateke, The Cheese Pit, Sam Choy’s Poké to the Max, SeoulBowl, Theo’s Gyros, Alaska Weathervane Scallops.

Sorry, no lineup for the beer garden, but you can buy tokens for tastings:

And heaters are set up!

This is all scheduled to continue until around 4 pm, near Alki Bathhouse (60th/Alki), with a costume contest coming up pre-plunge, shortly after noon.

ADDED 7:06 PM: Thanks to Robert Spears for sending photos from the costume contest and plunging!
