I go down to Summernats, have done for at least 5 years.
I totally appreciate the trouble and nuisance that must effect the locals for what would be at least a fortnight. There is obviously no point what so ever in debating the event, it is what it is to be honest, a bunch of blokes and female attention whores (in the most part) getting drunk and generally having a cracker of time if that's your thing.
But to say the people displaying their cars don't have serious money invested and aren't show cars is totally off the mark. I come from a circuit racing back ground and Summernats (show/burnouts) isn't my scene, but there is certainly serious money and heart time pumped into high quality show cars and performance cars at the event.
Plus, the local strip joins do a smashing trade during the period... If that counts for something...??? Guys ???
PS. I'm not a Bogan (ie... No Tats, No JB, No Singlet, Not a Tradie...)
