If anyone has some time to kill this coming weekend (Oct. 13 and 14), the American River Salmon Festival at the Nimbus Fish Hatchery and Lake Natoma State Park may be the ticket. This is a great opportunity to tour the fish hatchery and get some insight on salmon. Bring the kids along. By the way, it's free.
Here is the festival website address for more information: http://salmonfestival.net/
