To be honest Parkwood Springs isn’t in a great area but its not that bad.
I think it attracts scroats from other parts of the city as well as maybe the more immediate situation but I gather they are far more interested in ripping off the cars as they are a much easier target – afterall there are usually a number of riders up there and the risk of ambushing one and getting caught is quite high.
Plenty of dog walkers around as well.
At the moment though it is too cold and wet for tealeaves to be lurking around.
Usual rules apply – don’t ride on your own and don’t shout your head off about how much your bike cost and if you see a log across the track ride over it.
There isn’t actually anywhere for someone to hide on the downhilly bits really only on the ride back up.
I haven’t actually heard any confirmed reports of anyone being mugged for their bikes.
EDIT – I live about 5 minutes drive from there and have passed it countless times so know the area well.
