On leaving the ground on Tuesday, near the burger van corner, I came across a couple of people who had fallen. The injuries did not appear serious and they had plenty of people around them giving help so I did not stop. I did not witness the accident but I believe they walked into upright barriers [the sort of barrier used to stop people parking outside an office block] , there is a line of maybe 4/5 barriers presumably to stop cars exiting through that gap. They are painted black so difficult to see particularly on a dark wet night, I hope someone who was involved or saw the incident will contact the club. Some high viz paint might be a solution if these barriers are necessary.
