I have been there. If you have any specific questions about what the general area looks like, just shoot.
If anyone else is considering a visit : I can recommend it. It's one of the eeriest places I've ever been. The weather was very bad so I was there all alone at dusk. One thing will all always stay with me : the distance from the waterline to the bottom of the dunes seems like a mile...
Also came by Pegasus Bridge and Villers-Bocage.
