Favorite Thing About The Beach?

I had a nice little end of the semester vacation. No not to Destin or Panama..I went to Grand Isle, La!  I bet you didn't even know they had a beach there, ha.  Well I went for a run to "kinda" work off all the fish and shrimp, etc that I ate- and I found this little critter. What is your favorite thing to do at the beach?  What's your favorite beach food?  Who would you like to be on the beach with?
