16 races hmmmm?

I gather that they are having the usual Harness meeting as well?
Could be that they are trying to get the younger punters interested in gallops and harness.
It has been raining steadily in Melbourne overnight and I would be worried about the state of the track after that many races, I would imagine that at least the track will be downgraded for the night meeting unless of course they are moving the rail out for the last 7 races.
I've yet to see the quality of the fields for the night meeting, but I would imagine that it would be akin to Open handicaps at the provincial circuits.
The bottom line is: bet with caution at the night meeting.
