If there is any other way I may be able to assist let me know. Have you checked with the Churchill Medical Center.... you use to book the public hall through them.  They could tell you where to go to book it!  Tried the Yinnar Pub???  Ask Trevor there.  What about the Yinnar south school hall????  Susan
