I brought you to this park because the views of the CBD skyline are quite spectacular at night and well worth the effort of going to see. The park itself is well developed and attractive, and has an active community group looking after it.
A warning - the park's trails are used by bicycle commuters and they tend to travel at speed, so it's safest to keep an eye out, and listen for bells.
THE PARK:
For information about Westgate Park, go to this website.
THE CACHE:
From the starting coordinates, follow the trail of yellow reflectors.
Along the reflector trail, there are five red reflectors where you have a question to answer.
The questions are: (in order of how you will find them on the trail)
A = Take a seat and enjoy the view. How many red lights are on the chimney?
B = Count the 'floating' stones.
C = How many sides on the seat?
D = Take a seat and count how many lamp-posts on the bridge reflect on the water in front of you. (Hint: It's less than 8).
E = How many blades on the windmill?
GZ is at:
S37 49.(E-A)(C)(D/4)
E144 54.(D/4)(E/3)(B/2)
You can check your answers for this multi on GeoChecker.com.
ONE MORE THING: There's a BONUS CACHE along the reflector trail - see http://coord.info/GC4D5MW for more info.
