Couple of points. The MSA ruling has been in force for years and there has been no reason to ignore it and break the law. Want to risk everything?
It's no hassle. Try doing a cross border event from England to Wales as I have C of Cing the Wyegate for years. That actually is the biggest bind as we pay 2 sets of fees. The one to Wales is slightly cheaper even though its 70 odd miles than the English one for 20ish.
Anyway, date clashes. ACU fault. The mess about with the national dates and thus at CtoC level we can't set a date.
Every year we clash with Adrian Moss's events or would do if not careful and I am sure other clubs. Why? Because there is no way of knowing what some one else is thinking , short of having one whopping big national data base that is a first come first served set up. Quite how one centre is expected to know what one the other side of the country is doing baffles me. Dates in the Western centre are short and clashes out of centre will happen.
I suspect that those who worry about clashes are not really aware of the dates issues Eg we can't use our Wyegate start on Mothers day for example. Maybe I miss something?
