Lost sunnies at knapsack

Hi all i know its a little off topid and indeed slighlty off tne trail,but i just lost my favourite sunglasses along the path between the bmx jumps and lennox bridge so im a little desperate, re traced my steps a bunch of times but no luck,if any one comes across them please send me a message. Was my first time riding through there in a decade, great to see it all so legit after the dissapointing vigilante mobs of the lower blue mountains bulldozing of my childhood trails!
