On my travels through the Northern Territory and South Australia, I kept noticing ThE CARP’s stickers…
Oodnadatta Track – Painted Desert Road
A Skylark rocket at William Creek
This yellow one is at Curdimurka
Not just stickers. Look what I found near an old railway bridge…
Do you know who ThE CARP is?
From a little searching of the internets, I only know that s/he is widely travelled, and that stickers have been appearing since 2009 (or possibly earlier).
