I've met a few in Kuta, one asked me, "do you surf"? i said no and he was stumped what to talk about, you met any? you could have tried to brain wash them about Christianity
I've been three times, the bogans are centralised in Kuta for surfing and partying. When i travelled around the island i never noticed them again. You'd like Ubud, more chilled vibe, bogan free zone
