Please keep away from Winnies. It’s not allowed to ride there unless you have permission. You will get it closed down if you get caught without permission.If any riders are there they will chase you off, mayby even beat you up for being there.
Access to there is very limited.
Even mentioning it on the internet is bloody stupid.
Also if you get hurt there nobody will find you for a few days.
Do yourself a favour and stick to the Marin.
