It’s officially that time of the year to mark your calendars and save the date for the glorious return of Seattle’s favorite annual jamboree. Rainier Beer’s ‘R-Day’ will return to Georgetown on September 21st to celebrate all things quirky and magnificently Mountain Fresh with an eclectic music line-up featuring Allah Las, Sheer Mag, Monsterwatch and DJ Prometheus Brown and fun-filled activities filling the streets of Georgetown, directly in front of the original Rainier brewing site (hint: not the one with the R on-top).
