Andy, if the weather remains dry, this is always a good season closing event (if a bit cold when the sun goes down).
There should be some enntertainment in the form of jet cars and fuel funnys and dragster - watch for the header flames after dark.
Sadly, I'll have to give it a miss this year due to major house modifications and pressures upon me to complete the plumbing (currently no hot water, heating or cold water feed to the toilet!)
