Here's what you can do at a beach park.. you can walk your dog, or you can hang out  with your friend, or give your self a comfort by fishing. Some people just stand there on the beach, enjoy the wave.
Or.. you can simply take photos of sunset like this, or this.      

I once tried to make photos of water drop. It was difficult. So i want to share it here, and am hoping that i can get some critics These photos were the results.
