That would not be fun.
Was just checking out videos of the damage, and noticed this vid, shot from a helicopter travelling along the Seawall.

The Seawall is looking good, if a little nibbled on at one end. Looks like it did its job astoundingly well, too - almost everything that was *behind* the century old Seawall is more or less intact, if a bit waterlogged. Impressive.
Anyone who was behind it and stayed through the storm owes their lives to a group of long-dead engineers who built better than I think even they knew. We don’t build that way any more, more’s the pity.
