I was looking for information on using old skis to form hoops for hoop houses when I found this:
Ski Yurt: Upcycle of Downhill Skis for a Shelter in Cacine—Guinea-Bissau
https://link.springer.com/chapter/10.1007/978-3-030-33323-2_7
I can't read it all right now, but key to their usefulness is their resistance to termites.
This makes me wonder about skis as stakes for fences and the sides of garden beds.
