The primary issue is kids on minibikes - they will not be tolerated fullstop. Zero tolerance.
We will tolerate adults on 'pit bikes' who ride responsibly, wear a helmet and already have a wristband for riding....for transport around the complex. That is only if it doesn't get out of hand and/or the track operators direct us to call it quits. In other words we're prepared to give you a bit of rope, just be careful you don't hang yourself.
