KBKW Radio is reporting that Transformers: Age of Extinction will be filming at the Satsop Business Park in the Port of Grays Harbor in Washington state. The info was confirmed by Executive Director at the Port of Grays Harbor Gary Nelson who said "Paramount pictures has, you know they were going to be filming earlier this summer and they got delayed until late September, early October. In the agreement we had to sign they said they may refer to it as something other than Satsop." The business park is described by Alissa Thurman as "Satsop is a unique setting, from [two unused] nuclear towers to our surrounding forest, we can provide a variety of locations for filming all in one convenient park setting." It is not specified if the towers are part of the filming or not but it does seem like the kind of think that might be of interest to production. Thanks to Wynton R. for the link.
