According to the CLMOOC week 4 Make Cycle 4 email a pile of tyres is just a pile of tyres and nothing more.
This is a pile of tyres waiting to be recycled. The mountain in the background is a pile of shredded tyres. According to Wikipedia:
tires are among the largest and most problematic sources of waste, due to the large volume produced, their durability, and the fact they contain a number of components that are ecologically problematic.
Tyres take up valuable space at landfill sites (hence the shredding above), tyre stockpiles can be a health and safety hazard, and tyre recycling and storage can apparently sometimes be associated with illegal activities. Eek!
Some piles can tell a story or remind one of our shared history.
A pile of tyres is never just a pile and nothing more.
Tyres can also make great swings.
As I was writing this, Simon posted this great post.
