Comment: Kalbarri to Geraldton

Hi Grundle, it isn't a very scientific method, I'm afraid. I ask the locals and if they don't know, and it's a small town like Kalbarri where there are only three service stations I drive in, check the price and move on to the next one. Otherwise I just take what I get. I also use coles and woollies vouchers which my brother laughs at.
