I think they are trying to keep the fire from jumping the freeway (152).
We have a small station in San Martin, I think, Morgan Hill? I don't know. But we also have a small airport in San Martin. Yesterday I saw a helicopter taking off, it looked like it was heading towards Santa Cruz.
I've seen all kinds of tankers and helicopters stationed out there. It's distracting because it's right off 101. Anytime something is coming in for a landing or taking off, people start slowing down to watch.
