Rodger - disclaimers not necessary. We have sorted that bit out. There is nothing to disclaim against and anyway the minute you say 'we cannot be held....' it usually means that you can! Anyway we have debated this long and hard with the insurer and Tony, but thanks for the offer.
As to running it - I'd be more than happy to join in with Jon and Rodger et al in doing bits where I can. I was going to run a 90 handbrake masterclass, but seeing as I may be a little deficient in the 90 department by then, I may just be giving quad bike rides to people!
