Went camping this weekend near Colfax, CA at a spot right on the American river. The water is all snow melt from the Sierras, so it's clean as fuck (and pretty cold) but perfect for relaxing with a beer. Inner tubing not recommended unless you want to end up 10 miles downstream. Come to think of it, it's amazing that no one drowned. I think the worst injury I saw was my friend whose legs got mauled by one of the swimming dogs.
Sigh, back to real life.
