What's wrong with this picture?

I went kayaking on Thursday with a friend. Found some interesting conditions to paddle in. Part of it is shown in this picture - can anyone tell me what looks weird?
木曜日に友達とカヤックした。面白い状況があった。その状況はその写真で見ることができるだろう。状況をかるか？

We paddled out past the Golden Gate Bridge toward the Ocean. Had a nice view of the moon rising behind the bridge on the way back in.
ゴールデンゲートブリッジの下で漕いだ。帰ったとき橋の後ろ月を見た。
