Gday all, Could someone please help me get started building a track,I dont even know where & how to go about it. The track I wish to build is the circuit used for Australia's 1st motorcycle GP, the 1924 Bungonia GP near Gouldburn measuring approximately 84km(52miles) per lap. My first stumbling block has been how do I trace the track out? Ive tried doing this in Google Earth but can only go so far before the page needs to be scrolled on, which is when the line/polygons disapear. Is there some way of doing this through Google or should I be using the GPS set up? If it is to be done through GPS,do I have to actually drive around it or can I just download a GPS map? My track preferences have always been towards road race circuits such as the Isle of Mann, Irish & New Zealand Road Racing and the old Australian road circuits as typified by Woochoo incarnation of Longford (which I cant wait to try). Any & all help would be appreciated.
