Kyron, If they overwater enough to fill that ditch without it soaking in, where is that water sitting with a berm built up? We have this problem now and it sits on the racing surface at the apex that never gets rolled in, splashes up on the hard slick surface usually because of traffic and makes for a dangerous couple of laps. If you find the collection point of the trench cut another so it drains to the infield. Not much volume needed to move unless a real mistake or rain which probably made an un-raceable surface anyway. Well I have a couple of converts, now to talk to the grader operator.
