I just wrote them too, and this is what I got for a response
"Thanks for the email. We appreciate your interest in visiting Oakley when you are in town. Hopefully I can clear up the apparent contradictions you have dug up. Official tours of our headquarters are currently unavailable. We have offered them in the past and may offer them again in the future, but for now they are unavailable (we are experiencing a widespread turnover of the department that typically handles the tours so they are shutting the program down for the foreseeable future).
While official tours aren't available, you are more than welcome to come check out the building. You will have access to the front of the building (where our company tank is usually on display along with our WWII torpedo) and the lobby which includes our lobby store. While it's not the same as a tour of inner workings of the headquarters, its still a cool experience and a site to see.
