Several friends and I are planning a road trip from Boston to Myrtle Beach for spring break. Does anyone have any suggestions of interesting sites on the way and good (preferably cheap) places to eat. For example, we're driving on the Chesapeake Bay Tunnel-Bridge and are planning on eating at South of the Border in South Carolina, which was featured on the Food Network as one of the kitschiest restaurants in America. We've actually been looking for restaurants that serve giant foods (12 egg omlet sort of thing). Also if anyone has any suggestions for fun things to do in Myrtle Beach, that would be great. Thanks!
