Ah! Now,
Show People? That's a whole different ball game.
Yeppers. Your Ling people could well have been 'Travelling Showmen'. Ye might find them " Living in caravans ", the whole shebang. Bob's book focuses on " Gypsys ", see?
There was a lot of cross over ~ Ayres springs to mind as a name associated with both 'proper Gypsys'
and Show People.
So, working on the basis that smoke generally has to come from somewhere? I'd start digging around the more Show Folk dedicated areas

Try running a Search, on this board, under " Show* ". I've seen dedicated Showman sites listed here. That may narrow ye search down
