All great points and agree totally agree with all points.
Apart from one

. The age for the Marshalling. Ed and will are only 9 and 11. Now please someone let me know if I am wrong you won't offend me but I think they are fine and even at the nationals I have not had a problem. My only reservation would be if I could'nt find someone to marshall for them. I often race in the same heat.
However on Saturday there were some children marshalling that were just far too young so you are right to bring it up and make a suggestion.
Everything else is spot on. The token idea is fab and I also like the deposit idea as well. With the token idea I bet the track will be done in 10 seconds flat.
