I don't bet, but I've been to:
Ellerslie (home track and best in the world...I would say that wouldn't I?
)
Avondale (secondary home track)
Pukekohe (3rd home track)
Te Rapa
Matamata
Te Aroha
Ruakaka
Tauranga
Hastings
Trentham
Riccarton
Epsom (UK)
Lingfield (UK)
You guys have probably not heard of many of those!
