Well the dates in the original list are STACK events. This is where STACK is running a National Competition at a festival or on a Sports Field. Because the arena is there and the PA is there etc then it is an easy thing to have a Trick Thang.
Historically there have been a number of other festivals where Trick Thangs also take place. For the past couple of years I have been organising the Trick Comps at Bristol. As I am STACK National Director as well, it sort-of made them defacto STACK events. But that is about as far as STACK went with them.
Unfortunately in 2006 my kite schedule is much less than previously (shrugs). I do expect to be helping the NKG with a couple of Trick Thangs this year, but it looks like it is someone else's turn this year for events south of Coventry. I might be able to turn up and judge at Bristol, but I certainly will not be able to set it up and run it.
