Are track covers the answer though,if it raining at the start of the meeting the rider’s won’t ride anyway,and using the covers on the bends makes the track patchy and difficult according too stories I’ve heard ,also the track has to prepared when they are taken off.They are labour intensive and require a lot of volunteers.Saved a couple of meetings at Berwick a few seasons ago ,but for some reason even they gave up on them now. No win situation IMO.
