So, a couple of observations:
First - the saying 'happy wife, happy life' always trumps 'it's better to beg forgiveness than to ask permission'.
Second - when you find a practically new Jumbo Joe on Facebook for twenty bucks, you don't pass up that deal.
As you may have gleaned by now, I need to cull the herd a bit. Considering that I got the Smokey Joe for the express purpose of having a traveling grill, and that I got the Jumbo Joe because I wanted something bigger and easier to use, it stands to reason that the Smokey Joe is the one to go. The issue is what I should do with her. The vents are all present, but they don't seal particularly well. Even if they did, there are a couple of holes in the bowl that make me reluctant to even get too vigorous with cleaning. The wing nuts on the legs have turned into lumps of rust, and the legs themselves aren't in great shape. The lid handle came loose some time ago, and it's been re-attached with a couple of #6 screws and nuts. I only paid seven dollars for her, though I did replace both grates, so I'm in $26. I've gotten that much benefit out of having her for the last few months, so if the consensus is to send her to the great cookout in the sky, I've got no problem doing that. I would save the handle, though - it's in pretty fantastic shape for the condition that everything else is in. It wouldn't be too difficult to drill out the rivets, pull the handle, and drive two nuts into the lower piece to let it bolt up to a rivet strap as a replacement. I'd hang onto the grates until I find another SJ that I can't live without.
There it is. I pretty much have a plan in place to salvage a piece of her that can live on. I'm just questioning whether I'm being too quick to give up on a grill that's roughly as old as I am.
