"I'm a truck driver, and it's been a long time, if at all since I've seen anything that big. I mean it's huge," said Paul Andree, Fontana resident.
It's a nuclear reactor head, built in Korea, on its way from Long Beach to Arizona. At 19-feet in diameter, it's too wide to transport by train. And too heavy to fly by plane.
And just another example of how big this thing is, we went around and counted how many tires are carrying this load, 108. They also had spares in case they need them.
Which they might. At four miles an hour, travelling only when it's dark-it's going to take a while to get to Arizona. During the day, it sits. Thursday it was parked in Riverside.
"Ever since I was a little kid I've been interested in stuff like this," said Ed Worth, Riverside resident.
After hearing it was here, resident Ed Worth thought he'd drive by to check it out.
"I wouldn't want to be on there when this thing is going down the road," said Worth.
He wasn't. But Jesse Aronson was. Stuck behind it, all the way home the other night.
"It was almost a three hour drive to get home from Disneyland the other night. It was very frustrating," said Aronson.
Just for the record, they say there's nothing radioactive inside.
"Hopefully they're not lying to us, I'm not concerned, I think it's pretty safe where it's at," said Aronson.
Friday it will start moving once again up the 91 Freeway, and eventually into Arizona. So now you know. It's big, it's blue and pretty soon it may be coming to a neighborhood near you.
