I was 10. I recall in Cape May Point, huge old houses that were actually on the beach. 4 of them. All gone. The one that did survive was moved inland 200 ft or so after that storm, it is the rectory for the nun's summer retreat.
I saw tide swirling all around and under the convent building. I walked along Beach Drive in Cape May the day after, there was no road surface at all, and the man holes were way above my head.
My family and I saw Convention Hall gutted with the tattered curtains from the stage blowing in the wind. EVERYTHING on Beach Drive was destroyed, tsunami damage.
