Yes, top quality turf looks fantastic if treated well Robert but I suspect people were not encouraged to walk on your display, esp children. However, I understand completely the points you make and the aesthetic merits of a fine grade lawn
My own first class lawn looked great for 3 years or so but was not practical and took so much of my time.....removing the odd rogue grass by hand, close cropping three times a week and replacing worn areas on a regular basis plus top dressing twice a year plus ..............
Have to say though I enjoy your knowledgeable posts
