So close PEZ! If only you had answered in the form of a question. The correct response should have been: "What is an unused 1998 Stainless Steel Performer?"
I presume your clue was the tiny fragment of the therm-holder? Well, OK, you get the prize - presuming you'll be there. It's not THIS unused grill, but it is an unused grill, and it's a Weber. Do I have your attention?
More door prizes for attendees to be unveiled at the event. If you show up, your name is in the hat. (SOs and kids too!)
