By the time of the Mauger away guest facility of 1984 the decline had well & truly set in. Crowds were big compared to today’s levels but had dropped since the 1970s & track closures & those facing closure were increasing.
The whole reason for the Mauger ruling was to get Exeter to move up from the NL to boost the top flight & try to at least make them competitive.
The Mickey Mouse rules had started to erode credibility by 84 & that process has only increased since then, 43 years on & non of the warnings have been heeded & the sport now faces total collapse in the uk.
One or two promoters on the 70s/80s could see the issues coming John Berry was one as is clearly outlined in his books.
The other Stewkesbury who wasn’t everyone’s cup of tea fan the NL in the late 80s & ran the league without guests & some of the other daft rules that operated at the time in the BL. In addition the NL circuits had dirt on them which helped to improve the spectacle while offering lower running costs.
The NL at the time boasted more tracks than the BL a more credible competition & better crowd levels. It ultimately met its demise with the amalgamation of the BL & NL prior to 1991. This brave new world was then doomed to fail because of the infighting by the former BL promotions not liking promotion & relegation.
30-40 years on nothing has really changed has it, apart from ever declining attendances.
