Yeah the museum is open. It's neat but there's not much to it. Many of the items in there are beat too, lots of pairs with trashed lenses. Most forum members take more pride in their collection displays than Oakley does.
Where does the HQ tour take you? Were you able to see manufacturing or just the outside of the building?
My tour took me just about everywhere in building.. R and D , employee store , cafeteria, The Engine Room (hidden bar) walking by CEO'S office , saw the manufacturing of lenses and frames. also the dipping of frames...lobby. I doubt that any mores tours will go on since they let alot of office people go from there and as far as I know and a lot of the building isn't being used anymore.
