They are saying that as the group leaders are not actually instructors (they are not listed or advertised as them).
Also that as anyone that gets sent to hospital as a result of an accident whilst on track is potentially taking away availability of a space that a local person may require.

It would seem that apparently, get ready for this.....motorcycling is dangerous and they don't really want to be involved with it.
So unless we can get 3 qualified instructors to come along, this is now dead in the water.
