Went to a camping in the Laurentians in Québec (Ste-Agathe) and there were those things near some camp sites. The sites are only accessible by footpaths. No car access. And if you bring a bike, you have to walk it up a hill, so I doubt they are bike racks.
EDIT: I have sent an email to the park and they have been kind enough to reply. It's just a type of fireplace with a grate. They didn't give more info than just this. Thanks to everyone for pitching in!
Fire goes under the bars, food goes on the bars.
You know, like a grill.
What kind of food is going to sit on that? You cooking a whole leg of something?
You could probably get a tomahawk steak to work on there, or a whole, bone in long pig thigh.
Something wider than the gap between the bars, I'd assume. Or a pan.
You've never grilled anything, have you?
I have grilled many things.
Have you ever grilled anything on a contraption like in OP's pic?
Maybe!
