Remember the Rainier Beer sign on the old brewery next to 1-5 in south Seattle? It's being restored prior to being installed at Lake Union Park on Dec 29. Complete fun challenges involving Rainier beer -- like have the R shaved into your hair, or carve a Grazing Rainier on a gourd! -- and you might win a ticket to the re-lighting ceremony. Very cool social-media campaign for a nostalgic brand.
