This is my Weber. It has been by my side since 1994. As you can see, I have never bothered to cover it. The leg sockets rusted out about a year ago, but the new set up works fine since no one uses metal trash cans anymore. I could buy a replacement for $99, but nothing can replace the memories of all the ribs, burgers, turkeys, steaks and chicken I have cooked on "The Old Reliable" over the years.
Replacing that grill would be like casting a new Liberty Bell; it would not be the same. It may not work as well as it used to, but neither do I.
