The in laws holiday

My in laws were making a trip to Rotorua as they had read about it and really wanted to see all the mud pools and geysers for themselves. They flew in from the US and I had sorted them out a car through car hire rotorua. My father in law was a bit nervous about driving on the opposite side of the road to what he is used to, but I assured him that as long as he kept the steering wheel by the centre line he should be ok. Coming from the desert they had never seen anything like what is in Rotorua.
