My dad took the tour some time ago. To the best of my recollection, his advice was to get across the beach and into heavy cover as quickly as possible.
I had an uncle who took THAT tour. He mentioned that the scenery was beautiful but that the beach was awfully crowded with Germans.
Thanks to your Dad, we can visit and pay tribute to him and all those who risked - and lost - their lives for our freedom and liberty.
We owe them a debt we cannot repay.
