We had picnic lunch there. No, I didn't prepare anything. We just brought some food from the convenience store. Iki and Hiro played with the sand and the cold sticky water, and explored around excitedly, while I sat alone waiting. Ah.....this always happen lately. That Iki loves playing with Hiro, and that I have to kill the time alone (_ _!)
We also visited a shrine nearby where Hiro and Iki prayed a bit.
We didn't stay long. I felt the wind was too cold and was afraid to catch a cold (which actually really happened!) But it was a good relaxing one. I think it was a good change from our regular camping trip.
