ok random I know right? Well in 05-06 I used to live in Rialto, CA and there was a large stretch of unfinished highway called the 210. It was set to open. Well I remember they were filming a movie using the not opened yet stretch of the 210, but we couldn't see a movie sign or anything like that, just a bunch of cars (honestly didn't see anything that looked like the transformer cars but I heard they were kept tightly under wraps) so we figured it was some car chase scene and after a week they were gone. Well a year or two later Transformers came out and I didn't even think about it, in fact i didn't even think about it later until right now. I am watching Transformers and the scene where all the autobots are headed to the city with the cube and Barricade and Bonecrusher arrive I saw some things on the side of the highway being constructed which yes a home depot etc was being built there at the time, then I saw the highway sign for the exits and yes it is the 210. I looked it up and sure enough that is where it was filmed. I now feel completely stupid that they wre filming transformers there, I saw it, (well not the actual filming) and didn't even realize it until all this time.
