Brush up on your Lindy Hop and head to this one-of-a-kind ball that celebrates all things 1940s each June. A hangar at the Boulder Municipal Airport is transformed into a dance hall befitting the USO, with 1940s cars, celebrity impersonators, swing dance lessons, live music and an authentic-attire contest that’ll make you feel like an extra in “Casablanca.” 
The sun made us lazy, and after following Brian as he made his way upstream I found a wider expanse of sand and gravel, promptly plopping down on a pair of flip flops I had brought in my backpack as a make-shift seat. After identifying the northern harrier hawk over my head, and the savannas sparrows and red-winged blackbirds perched precariously on reeds across the water, I took out my knitting project. I didn’t have to worry about losing Brian; in the valley I could see for miles in both directions.
