I love the shows and also drag racing thats why the hot rod drags is my favourite event of the year.
I have one improvement idea though.
Not everyone with rods can get to race or wants to race, but it is a shame their cars stay by their tents.
My suggestion is to mark off an area inbetween the main tent and the club house for rods only to park (A bit like the show field) This would give everyone an area to show off their pride and joy and visitors not only get to see great old school drag racing, but also a show and shine type event as well.
This worked well at the all stars event (Which was not as popular as it should have been due to being run on the same weekend as the Ipswich show).
