could be a bit of mud, we had a nice bit of rain over night and today, should be a bit more tomorrow and early saturday hopefully.
stacking up boulders? dont know what part of the track he did, but we never had to do that...however there is actually a few mundaring tracks, but the powerline track is the only one we can LEGALLY do. as mundaring is a large water catchment area, you'll get your ass handed to you if you get caught on the non-powerline tracks since its all a 'protected' area or something like that.
lol yeah, kids are fine. i'm only a young guy myself at 18 years old XD
and dont worry, there are HEAPS of chicken tracks! dont worry, the few of us that have been before will tell you which way to head so you got no worries.
