Seriously why do the majority when posed this question talk about schools? It's bonkers. Schools offer sports they can deliver on their grounds. I'm not convinced that's the answer though there is something in what Greg is saying about the attitude of clubs. If there is a way to incentivise clubs to open up slots or develop short beginners courses... I remember playing at the Valentines Park pitch and putt in Ilford when I was younger but there was no link to anything else so perhaps linking a collection of P&Ps to local clubs like the way the Secondary / Primary School clusters work could help...
