Hi Slice of Heavan
I didnt know that is very interesting - thanks!
BTW can you get them to turn those bloody lights off at Murray bridge - MB have seriously contributed to ruining our fav quickie darksky site of the last 11 years! Specially that stupid prison with its stalig 17 floodlights - we used to have beautiful dark skies there! (along with the $ signs in their eyes developers turning Williamstown and the Barrossa into some kind of retirement destination) I know its not your fault mate just kidding

dont shoot me!
Bah! hate the real estate boom and single occupiers and - it seriously sux - bring back the recession we had to have!
