We were driving up the Tarras Cromwell highway and noticed this unusual feature in a road side paddock. This is surely deserving of a cache. Perhaps "Steam Punk" has reached this region?
It now appears that the man has moved his bike but the cache is still there, good hunting.

If you want to see other Steam Punk creations a visit to Oamaru is the place to go to.
The cache is a bison with log only, BYOP.
