tdunster,
Yes we drive them for fun and race them for cattle stations...

A few of us practice at a local track that is open and free to the public to use, so that we can be faster at big events. The usual club scene is normally friendlier than the large events, because people at large events are competitive and want to do their best.
What we find through practicing is how far we can push the cars, revise setup and test tyres and inserts, so we can then share with others who ask questions on this forum or word of mouth. As you find when you go to different tracks not all tyre combinations work and on a mini your tyres are your major tuning tool.
A lot of us are friendly, approachable racers who will provide answers when asked. It just happens that some ask or make unsubstantiated statements which rile others at times, especially when they do not know all of the facts as to why they use or do different stuff with there cars. Each to there own, as we all play by different rules.
The idea of getting out and having fun is really the best part of mini racing. As you have said a track, a group of racers and a fun time can be had. Even when your having fun the competitive side will come out.
BTW
I think you will find most of us have so much mini gear we could open a small shop. Anyone for a slightly used MO3 with some steak knives.......
Anyway enjoy your mini's.
Calvin.
