Hi Michael,
I might as well ask, do you have the Canberra radar for the 8/12/2004? If so, can you email it to me? I am really interested in seeing what really happened. That day was my first 'storm chase' and easily the best storm structure I have seen. I also got caught in the core of another storm with hail around 3-4cm (I guess) which put some small dents in the car and chips in the windscreen.
