Hi Steve
What do you want to go to a show for ?
If it is to see tools and machinery etc then the DM show at Kempton Park was pretty good ( and free ) but that is not until October,
Just getting into this hobby and currently sorting my shed out so I just want to go and see tools machines etc...nothing specific ....I will try and book a day to get to Newark..go to car shows all over the country so Newark is reasonably local..lol
