“Pitch” - Very good.It's a lawn ffs !
And in a university town too.
I don't know why local residents and sportsmen don't pitch for some nice peaceful cricket practice on that grass.
Stop getting so het up, just go out and enjoy yourselves.
As with every game and practice it would be unfortunate if anyone were to get in the way of a bat or ball, but I imagine people factor this in and treat these minor dangers as acceptable when invading the pitch.
