Favorite Memory form Cat Tien

My favorite memory form Cat Tien is when we went to Bau Sau to watch crocodile. We have to walk five km to there and five km to get out. When we got to Bau Sau we can't see any crocodile, all we saw is a beautiful lake without crocodile. Then we dicide to playing card with each other. One hour later we backed to hotel. I think it was very funny because we must walk ten km to playing card.
