Is Micheal your brother? When they mention aerated concrete surely they mean a Thermalite or Celcon building block [:-)
I can't make it either as my trusty old van would probably collapse (and you know how that feels), maybe next year. I have very fond memories of Helensborough when I attended a GP14 Nationals there in the early nineties, shocking results right up to the last race when we had a flyer. Is the ship wreck still being used as a spacer mark?
I'll be flying up to Scotland mid August for a week, staying at Rosemarkie are there any Cat Clubs in that area as I can't see any little sails on my Atlas.
Have a good Summer and I hope you have good weather for your Championships. Might see you Codblow.
