Hi David
The address is the mangrove mountain pony club ( historically known as McKenzie Park) and it is situated on Wisemens Ferry Road Mangrove Mountain
Mike, the originator of Iceinspace has placed a map at the top of star parties, it is quite easy to get to although I have never done it from the wisemens ferry end.
There is a lock on the gate which a number of us have the key to amd some arrive before sunset to get established before nightfall.
If you do make it we look forward to meting you. If you have a CB radio usually sittingon channell 11 these days and just put a call out for the pony club boys ( nothing like the village people)
