TheBoiledEgg said:new facilities and its alot cheaper to look after hard courts than it is to look after grass 52 weeks per yr.
also with advent of TV....... NIGHT sessions became possible
also public can use the hard courts to play on as well.
don't think that was allowed on the grass...... you wouldn't want dickheads and plonkers ruining your lawns would you ??
I know people did play on the grass at Forest Lawn. I know someone who remembers playing there as a teenager.
