Steve, I think you hit the nail on the head with your comment "there is little different now about Sheffield to 1978 / 79. Cars are very different and no longer suited to the style of racing i used to see when I first became addicted, many seem to fall to bits with any contact with the fence.
It's a shame because Sheffield as you say have some of the best facilities of any Brisca track and as I have said could be a fantastic W/F venue. Maybe only using Sheffield for big events may be the best option open for everyone, and credit must be given for you keeping it alive for so long.
