Getting this thread back on topic.
People seem to be quite busy Labour weekend. So probably not the best time to organise such a trip. Early October marks the start of the trout season so I probably would not be thinking about Surf Casting.
I feel any ‘WestCoast trip’ would be a real drama to organise and would have to many clashes. So the only real option would be Kaikouria or smaller trips to a local Beach in Marlborough and Canterbury.
Looking at the Calendar.
October: 20th or maybe sometime in mid November?
Would need to consult tides.
