Small entries may be down to a few things. Riding the same sections at two venues I know offer lots of scope puts some off. The cost of entering on the day? What is that now????
8 sections instead of ten and club officiakls strolling round, that annoys me most of all. Whilst some of the lads here like hard sections (Gary lives outside our centre I think?) I'm not sure it suits enough people.
I do remember them changing a section halfway through a trial a few years back as well, can't remember why now.
