Noel, are you serious with your question of just bored and looking for a bite?
Drags to me are not all that interesting, my car was built to handle and as such I would prefer to use it around corners where I have more fun. This doesn't exclude it from being capable at drag racing though. Having said that, to race door to door where you can overtake on corners etc is reserved for those with specific CAMS licenses, to the best of my knowledge the track day events that don't require more then a basic license don't allow you to overtake on corners hence removing the fun aspect of it for me.
Another aspect to consider is that many Skyline owners that I know use their Skylines as a daily driver and as such, don't race it all the time and save their fun for Skyline concentrated events where they can enjoy the racing with other Skyline owners.
Another thing to consider is that a VH Commodore with a 308 with some work done to it is a cheap fun when compared to a Skyline, and if they break something the repair cost and availability of parts make it even easier to fix.
Now, you said that you went to these events but did you participate in said events?
If you didn't then I would assume you have a reason for not doing so and perhaps that same reason may be why other's weren't there on the day. Generalisations are a problem though so I understand you don't mean everyone when you question the participation.
Cheers,
Ben.
