I am in Florida visiting the folks. Well, there is a bazaar run every year here that I help out with. Basically it sell donations giving by the local people. Well I was helping bring all the stuff down from storage and what gets handed to me? An 18 inch weber grill - a Jumbo Joe! Well, I told them to put it aside so I could buy it. I then bought a suitcase so I could bring it home. It is stamped N so it is a 1991 model. It is in really good shaped, it looks like it was well taken care of. The bolts came apart rather easily for a grill 18 years old. I have been looking for one for camping I am pretty happy. I told my wife and she just rolled her eyes.
