Vassago,
This was my grandfather from Texas so it was nice spending time with him. The best part was skimming along the stones of the American river. Certain parts open up into small lakes which are crystal clear. We put on our snorkels and found all sorts of strange critters at the bottom.
I think it was the place itself that made it magical. We camped in a valley which was surrounded by mountains and fir trees, and there wasn't anyone else around except for an old man who we'd see fly fishing every morning. I'd love to go back one day.
