Randy and I flew up to Oroville to meet Chris for lunch.
It was pretty smoky, but every aid said the visibility was at least 8 miles. Still, we were low, so it wasn't terrible. Chris had tried to get to Truckee, but ran out of visibility at around 6,000'.
We flew back down the Feather River, and the visibility was a bit better... we could see the Sutter Buttes, for example. Big Brother didn't see us until we got to Marysville :o)
