If you go back many years, then there was sever competition between clubs, and one didn't talk to the other or support each others events.
I'm pleased to say, in recent years this has changed significantly. Mainly due to the work of the Triumph Forum. This is where all the "management" of the various Triumph clubs meet up regularly to swap ideas and plan joint events. Such events as STIR, Triumph World Picnic, Triumph Marque Day, WCR40 and club National events.
We, and other clubs (CT, Stags, etc) ALWAYS support and attend each others National events. We have had a stand at the TSSC show for many years now, and at the Stag OC do, and likewise, they are always invited to ours. In fact, it would not surprise you to know that several of the Directors of this club are also members of CT, Stags and even the TSSC too........
So, its all good. I have been to the TSSC weekend before and throughly enjoyed it (not as good as our National though!).........
As for our National event coming back to the South East..... it is, next year! The 2011 National will be in Dover, then (I think?!) Nottingham, then Somerset then who knows........... depends who offers to run one!
