We will be attending my son's wedding at Edgefield in October. This will be a once in a lifetime trip for many. Most will have all day Thursday and Sunday, and most of the day Friday. What are some "not to be missed" options? Rehearsal dinner is at Portland City Grill, so everyone will experience downtown from the 30th floor. Grandparents are in their 70s and 80s, so no hiking, unfortunately.
