There is a very nice story in the Bee about rafting and hiking on the American River, even during this time of year.
An excerpt.
“The point is, if you live in the Sacramento region and you aren't using the American River, you aren't living well.
“This beautiful ribbon of water defines Sacramento, making the area one of the most outdoor-friendly places in the country. And there's no better way to enjoy it than in a kayak, assuming, of course, that you can swim.
“Each time you go out, even if it's the same run, the river and light are different. You may encounter playful river otters, schools of huge fish streaming beneath you or beavers diving with a splash of their tails as they see you pass by. You won't think about work or problems or politics or your losing football team. It's the perfect escape.”
