Why do the big owners avoid Flamingo Park ?

I see Molly's Chambers scratched for being the wrong horse - Is that 2 incorrect horses sent to races recently in this place? The need for a permanent stipe based there is glaringly obvious

TBH OTA, most of the factors you allude to are valid for most venues in SA, IMO.

OTA, Craig Zackey, Callan Murray and Muzi Yeni are all top 10 jocks,I cant remember when last a horse broke down in a race there, Double Bind (8yo) has run 12 time this year for a win and 9 places,Jaguar (7yo) last 21 runs has resulted in 4 wins and 14 places,(including 3rd place in the 200K race on Saturday) Dodgie Itie (6yo) 8 runs since his return 3 wins (including the 200K race on Saturday) 4 places and there are many more examples that highlight the fact that horses that run and are trained at the center remain competitive and sound into a ripe old age....

The old cliche that horses that competes at Flamingo Park are unsound horses dumped there are long gone. A lot of the horses that are vetted before they are purchased. Some are put up for sale and ends up there because of the price that the buyer is paying. A better price us paid by the trainers and owners who compete eagerly to win a championship/ title.
Sea Bean, Royal Master,Red Special are horses that raided other centres during the previous season with great success..
Dawson, Naidoo won great races on the day..can they do it on a regular base..I don't believe so.
