Pole position Multi-Cache

The cache takes you on a walk around the neighborhood finally ending up on a coastal boardwalk. We suggest you allow 1 hour to do this cache. Parking is recommended in Carrington Parade, Dick St and The Drive.

The coordinates for the final are accurate, however google maps for this area is misaligned - so please go by the coordinates and not by the map!
