I think the fact Berwick have a 100 percent record at home proves fans will turn up to watch a winning side at home. Throw in a cup final after knocking out the league champions elect as well and its no wonder the crowd was big.
Fans dont care about the racing on the whole , they want to see their team win.
Exeter were proof of this, great spectacle of a track with you being so close to the action but mainly gate and go, heavy home wins every week and they had good crowds right up until they shut despite usually being rubbish away from home.
Morris will be one of the signings of the season next year I am sure, he has been flying the second half of the season.
