Imagine the Possibilities

During one of my most recent visits to the American River, I discovered something very curious and imagined the possibilities of what this could be. At first I thought it was two crocodiles crawling into the river. Then I looked again and saw a rowboat with two oars. The next time I saw a huge heart with arrows piercing it. What do you see?
