Just throwing an idea out there in the hope these things get spread around for consideration as I believe they do.
Re the Adelaide Cup date debate:
Keep the current setup in sunny March for the social punters and second tier / progressive stayers, they need a race too.
Do something innovative and run a new 3200m WFA at the end of the May carnival for the purists, following the lead of the Dubai Gold Cup. Shift the underachieving Port Adelaide Cup to May as the traditional lead up.
Probably programming and practicality issues i'm missing but an idea anyway.
