Santacon 2017, Portland's tenth, was held on Dec 2, 2017. We saw over 600 Santas (and other assorted holiday costumes).
We visited: Dry Dock, Rosie's, Pat's Pizza, Lincoln's, Binga's Stadium, Port City Music Hall, Drink Exchange, Oasis, Bonfire, Gritty's, Bull Feeney's, Thirsty Pig, Grace, and Brian Boru. (I personally didn't make it to every venue.)
These photos are on facebook if you'd like to share and/or tag yourselves.
