And then it starts to rain and I realise that they aren't all that practical.
As we cruised through the country side of Hue the sky turned black and it started pelting down in the way that only Asian rain can.
I ordered an iced coffee but the guy quickly laughed and told me they only served beer.
It was 4pm and Jeff was starving so we decided to get some food to go with it.
A menu was produced that contained zero English and my limited Vietnamese didn't help, I didn't recognise one dish.
The guy spoke no English but between Jeff and himself we ordered what we thought might be a pork snack of some kind.
When a plate arrived on our own table I quickly realised that the rain had bought us a food rainbow.
In front of us was the most mouth watering plate of BBQd perfection.
The pieces of pork rib had been marinated in schzeuan pepper - a spice I was yet to come across on our trip.
The onion and tomato pieces in between had soaked up the pork fat flavour and had been caramelised in a way that only an open flame can achieve.
Dipping each morsel into the soy sauce only enhanced the peppery flavour quickly turning this dish into one of the best we had had on the entire trip.
After cursing the sudden down pour I was suddenly begging it to keep raining so I could keep ordering.
You never know what you are going to get in the middle of nowhere in Vietnam.
