I agree that the Wishing Well & Barrel BQ may not have been the most practical of designs, but they sure were creative, and my guess is that if/when one of them surfaces (assuming it is in decent condition) there will be a frenzy like when the first Ranger appeared a few months back.
I've driven by a few homes in our area that have wishing wells in their front yards, and I've always taken a little closer look, just wondering if they could've housed a bbq at some point in the past. I'm sure there aren't many - probably none in my area - but it would be cool to see one.
