"This is bad."
Q: How long do you think it will take to fix it?
"It wouldn't take them too long, see the problem is, right now, they've got a lot of things going on up at the canyon that's holding up freight right now. This would probably be a couple of days' job right here to fix this."

"The city of Yuba City has been evacuated. The urban area is pretty well out of the city now, under the mandatory issue of last night. That's probably around 30 to 40 thousand people out of town.
Q: And Marysville as well?
Marysville evacuated the same time last night.
Q: Are we talking close to 100 thousand people?
I think your estimate is high at 100 thousand, closer to 60 thousand.
Q: And where have all these people gone?
Like we were telling them last night, out. Find a road that's open and leave the vicinity."
