I was going to say Slim, look out for this lot lurking around kennel blocks with cameras, but you raised it!
If "they" can get into chicken farms then a greyhound track is easy picking. We are all issued with NZGRA cards, so anyone not official or connected at a track should be told to move on, and the club should be keeping an eye on this!
Any debate with Cross etc, needs GAP and the SPCA kept in the loop and on GRNZ side.
Having said all that, when I have talked to random people about my involvement in the sport you can see them think..then they say "what happens when the dog stops racing?"
I don't know if the equine community gets asked that question as much??
