I took a ute & trailer load of firewood up the mountains for delivery. The theory is, I unload the trailer at an easy access house, then drop the trailer and unload the ute where access is tight.
I must have been in dreamworld when I pulled up on a flat area to drop the trailer. Pulled the plug and undid the chain and started off up a narrow windy track to the second house. Was almost there when I looked behind and the trailer was still coming along behind me. Oops, forgot to unhitch the coupling.
Nowhere close to turn around so after a lot of cursing I get back to the flat, unhook the trailer and try again.
