There's no payment as such so I'd need to take 4-5 days off work meaning I'd use my own annual leave entitlements...

Nothing better than when you use your vacation days for something you love. Even if you arrange for your partner (she is your biggest fan) to go with you, it's a big hit! 🙂

I wish you a steady hand and good shooting. As many clean hits as possible (grandmothers with bags to miss) 😀
