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.
Second on firewood storage.
The sides keep it all in one place, while the top lets you throw a tarp over it to keep wood dry in the rain.
It’s definitely not a bike rack, the cross bars would stop it working.
It’s definitely not a grill. The concrete would be discoloured, and the base is all wrong.
Yes, precisely couldn’t pin point why it wasn’t a bike option, thanks, your point on the grill is exactly why I had crossed it off the list of possibilities as well.
I’ve been putting my tarp over wood directly—didn’t realize I was doing it wrong :)
If it had no top, the poles could damage the tarp, or it would be a pain to tuck it in around it.
