The park on QE2 Drive by Burwood roundabout would be a good venue, open paddock in front beyond the park edge for the unfortunate moments.
We held a casting day a couple of years back as we backed onto a schoolfield here in Levin. It was brilliant!
BBQ and bevvies accompanied the lies and the casting efforts and results were very revealing regards styles, weights, rod differences etc. Great for the in between days and gaps in the moon phase etc. Good media to meet other members too.
