You've probably just ruined this for the rest of us!!
Correct advice is
Get your mates to film it all.
Do some comedy "oh I nearly slipped there" bits.
Choose somewhere remote, estimate time to climb against time for police to arrive from nearest major road. Have a bike at the base for X-country escape; old bill aren't going to bother their arse chasing you but, if it's a quiet day, they might get the copter out and you'll get to star in one of those "documentaries".
