Since the corps' founding in 1948, the Cavaliers have been an all-male fraternal organization. But that didn't stop one female fan from marching alongside the Green Machine on Friday. Instagram user smallz_04 chronicled her day with the Cavaliers in this impressive four-part Instagram selfie, videoing her smiling self as the corps took to the streets of Chicagoland on the Fourth of July. We're happy to report that her videos didn't turn into a public service announcement on the dangers of marching and taking selfies at the same time! Always remember to #selfieresponsibly drum corps fans!
