But why is this event so desirable? Certainly you will see a good cross-section of the town there - and have time to chat. But more attractive is the army of our young blokes, and the occasional girl, their jaws set with determination learning how to overcome the fear as they rip down Drews Ave with their bottoms millimetres from the ground - pushing off at the top - then taking the corners and jumps at speed overcoming the gravitational forces of the "Wall of Death" at the top of the street - over the jumps - then down through the finish line at Roam Cafe.
To drive a soapbox doesn't require that much skill - but taking the corners and jumps at speed takes courage and commitment and does sort the heroes from the show ponies. Why this is important is that it is a voyage of self discovery - to learn how to suppress the fear - that strong sense of self preservation that we all feel when we are close to danger.
I mustn't overstate the danger aspect - it is really only a perception as the chances of getting hurt are minimal - drivers must use helmets and the soapboxes are examined to ensure that they have brakes and nothing is sticking out that could damage the driver. Personally I would include a sturdy jacket that would avoid cuts and abrasions. They do - occasionally - fall over.
The other benefit from this event is that all of these soapboxes are mostly designed and built in Wanganui. Depending on their age and experience the young racers will take a greater or lesser hand in the design and build of the machine. The soapboxes are of varying constructions - but what I have noticed is that they achieve a greater level of sophistication each year. Some manage complete rebuilds or perhaps just a little tweak to make the brakes work better.
With New Zealand's shortage of engineers I wonder how many young people will get their start by figuring out a modification to the braking system of their trolley?
It can be a great boost to the confidence of a young person to modify something mechanical, then risk their reputation on its success in competition. They can learn so much. I hope they do - but please - no one tell the thought police!
