1940s WWII Ball 
Whether you're nostalgic for the real 1940s or the Casablanca version of the era, don your fedora and head to Boulder for an unforgettable trip back in time. Swing dance to big band tunes by the Jeremy Mohney Swing Band and a crooning Sinatra impersonator (Derek Evilsizor) or try your luck at a roulette table inside a hangar decked out as Rick's Café Americain from the classic film starring Humphrey Bogart. After a late-night confetti drop and a radio announcement heralding the end of WWII, you'll be ready to party like it's 1945. Sat 5 p.m.-1 a.m.
