Mate, was it an Ozone bar & lines, the new one with the soft bar ends?
If so, you are probably out of luck, as last Thursday arvo (22/12/16) while we were waiting for the wind to come to come in, I saw an older bloke who had a limp head in, with his family & dog, from the sand spit with what looked like a new ozone bar & lines.
Didn't think anything of it initially, until i realised it may not have been his, as he didn't have any other gear, and he was a hobbling old bloke...
By then, they had left the car park, but I can guarantee you, it struck me as so odd, because I ride Ozone so noticed it in his hand.... that's when I thought far out, someone has probably left them out there on pack up and forgotten them...
Sorry to be the bearer of bad news mate...
