A few of us are going to the Chatham Dockyard again this year but you need to send in an application form individually and send a donation of £5 to enter. Unfortunately they are almost fully booked but I have checked with them today and they say it's not to late to apply if you are quick!
I have a form I can send to you so if you want one PM your email address to me or you can contact the organiser direct on
