Hey
Just found you guys on a google search, when researching Manly Dam. I'm pretty much a beginner rider, and today I attempted the Quarry track on the Cascades labyrinth. I went at it from down in the valley up (not the best way to take it), and found it incredibly difficult (I also got lost at the recycling depot-did you know you can see the city if you take th wrong turn-right intead of left-at the top of the trail), but I managed, and I still have all four limbs in working order. So i was wondering if there is a link to a key of what the colours mean on the google earth overlays, or would someone care to explain what they refer to.
