Mary Mary Multi-Cache

There won't be any Silver Bells, or Cockle-shells, but you will find plenty of women called Mary.

This is a simple but quite long cache. It will take 2-3 hours to complete.
There are 10 waypoints to goto and at each point you need to do some maths, so don't forget your calculator.
You will walk just less than 3km from the front gate to the final stash, so bring your hiking shoes and a bottle of water. (You can either walk, drive or ride your bike to do this one.)
The front gate is less than 250m from Sutherland station, so it is easily accessable from public transport.
