How strange, I just did a quick post on water. I live in Brisbane and we have just ended a very long drought which lasted many years. It has now broken in a big way and now, even though the dams are just about full again, water restrictions still apply and there is a big change in attitudes in the general population.
I doubt that anyone would consider using a spinkler to water their lawns or gardens again, or hose their car down for that matter. In the "olden days" people used to hose their driveways clean, I have not seen this happen again and reckon if someone tried this today they would be pounced upon by neighbours and berated, and then call the police at such wanton criminal activity, times have indeed changed.
