The residents of the small coastal communities along South Carolina’s Grand Strand feel the floors vibrate in their homes each year around the middle part of May. The cause is not natural in nature but man-made. For it’s the start of the annual motorcycle rallies that flow and ebb into the area each spring and bring in the start of the summer tourist season. It comes like a boxers hard punch to the face and floors the locals to the mat and into submission.
