Marrickville park has some unique features.
It has LAWN tennis courts.
It has a croquet club.
It has a nice cricket/football oval as well as cricket nets.
There's a martial arts club above the tennis club.
An excellent playground area.
It has a rose garden.
It even has a cache (or 2)
To find the cache use this formula: S33 54.(c-b-d)(c+d)(c+a) E151 09.(c-b-d)(c+d)(b+a-d)
A = the number of light bulbs on the light pole above the croquet club
B = the number of birds in the sculpture
C = the number of LAWN tennis courts(not the overall number of courts)
D = the number of croquet courts

NB. WP1 was originally in the centre of the oval (making this a mystery cache)but was moved to allow another cache in the park. This is why some people now say this is a Multi cache. I agree, but to change it means archiving/relisting.
Qba'g chyy, ghea.
