We drove to Seagrove today to make sure that all chairs and loose items outdoors were put away and all windows were locked (they weren't). We got online and saw that we'd have 78 mph winds at 7 AM. We also know that the bridges close at 40 MPH and were afraid we'd get trapped. So we're now on our way back to GA.
BTW the scraped sand was essentially all gone by 4:30 PM. The surf was already lapping up against the "cliffs" or former dunes. No wind when we left at 5:30 PM. I took photos, but the cell phone dialup speed in the car is too slow to upload photos.
