What I like about my club is...
Very little cliquiness, very supportive members and especially the organising comitee (I think this is key to making newbies feel welcome) and a suitible event where newbies can fully participate. In our case it's the Aussie Pursuit handicapped training night. Everybody get's to compete at their own pace, nobody gets dropped, anybody can score points. The fact that I've won the points trophy for last season is testament to the fairness of competition!).
The main ethos in our club is to try your hardest. That's what counts, not who's the fastest (we have TT's for that), but that you put in effort to improve week after week. That counts for a lot in our club (Didcot Phoenix CC).
