I talked to the lady there a bit more last time I was there. At that time, most of Weber had moved out with the store & maybe parts center left, along with some other small group at another location on the property. The Stephens family still owns the property, so I'm guessing the lease was up and either the current owners found something less expensive or the Stephens family had other plans for the property.
In any event, Weber told her they want her to move to the new location & it sounded like they might open a "temporary" store for the employees. She indicated they were talking about re-opening a factory store that would be open to the public in about two years. She did not appear to have any idea why so long before reopening. To me, she appeared hopeful, but worried, about her future at the company given the store closing, while they also said they wanted her to come to the new location. But, maybe I just assumed that is how she would feel as that is basically what I was thinking after hearing it.
