Have been to green man 6 times, however my son is getting older and i think i may be going alone this year and was thinking of stewarding. Anyone done this?

I haven't but it always seems like a nice thing to do, and I have often politiely enquired / interrogated the odd nice young person looking bored on a gate. I think they do 4 hours a day, and can be posted anywhere. If there is something they particualr wnat to see they can usually wangle it. You could end up being posted in a good / interesting spot or somewhere boring. I think there is probably a slight advantage to doing it as a respectable adult.
