In regards to the painted silo's in Vic ,We here in Qld also have a few. This one's in Thallon. Population about 260 its between Mungindi and St George .Not far up the road is the Nindigully Pub .
I went to Granville Island in 1997. I don’t remember seeing the silos. I reckon plain white would be pretty forgettable.I love it that you are getting out and about. But I must admit that most 'silo art' I've seen in S.A. and Vic. does little to impress me and I'd rather see the silos painted plain white. Yeh, I know most will disagree and I'll get howled down for suggesting such!?
I do admit that 'the proof is in the pudding', and it does generate tourist visitation to these communities. However, the artist in me would love to see more creativity (doing something original/different/more creative). This gives an example applicable to an urban site in Vancouver, Canada.
