Not bagging the PPT, but they need a little bit better planning, may be talk in advance to some of the clubs that they need support from for events like these.
Their first year was great.
2nd event, they organised for the same night as the Macquarie Uni Astronomy open night, talk about fighting to get a crowd, did they think this was ratings season.
This year, they picked a new moon weekend, 1) what do 80% of the public attending an open night want to see, the moon, 2) those that would normally want to help are away at a dark site taking in the joys of the sky themselves.
