Darbie’s Demo Derby committee was formed in 2007 when the Smith family & friends took over management of the Boissevain Demolition Derby.

The Smith name is well identified in the demolition derby and stock car race circuit as members have been involved in these events since the 1970’s. Darbie’s Demo Derby has been named in honour of Darlene and Robbie Smith. In 1997 Robbie Smith was injured in a stock car race and left a quadraplegic. His wife Darlene suffers from severe Multiple Sclerosis, relying mostly on a motorized scooter to get around.
