Google maps is your friend (HINT check out Fish Creek park!). Please be aware of the regs, as certain areas are closed presently, i.e everything north of the weir and section at just below the weir and within the bird sanctuary)...
Yea dude, haha youve posted like 3 threads about the same thing with no replies. Should be more specific as to where in the city you are, introduce it alittle better, and say please or thank you, and you would probably get more responses. Explore.
