New one on me ...

Tina and Tony Carter formed "Somerset's Festival of Transport" rally back in 2012 with their first event taking place at Bruton. Then the following two years they held the now growing show/rally in the grounds of The Haynes Motor Museum.
The 2018 event is being held at Frome Show Ground, Frome, BA11 5ES. On the 22nd/23rd September.
Tina and Tony put these shows on with the help of a few loyal sponsors and helpers and are always looking for more help.
The vision of the show organisers is to eventually be self funded and make a profit for charity. This can only be achieved with the support of the exhibitors and viewing public.
