The Shag is a legendary fast dance, influenced by the jitterbug, that grew up in the red clay hills and coastal dunes of the Carolinas. Originating in the late 30's and early 40's, the Shag was performed to the big band music of the Swing Era. Later, shaggers adopted the early rhythm and blues beats that would eventually become rock-n-roll. Shagging has gained such a following that it is now the Official State Dance of South Carolina. Many shaggers attend two large annual events; the Myrtle Beach "Spring Safari" in April and the September "Fall Migration".
