4G is infinitely safer and better than rock hard summer pitches. Players simply can't go to ground during drought conditions. However, there's still a tiny bit of give in the summer, unlike when the ground is frozen, in which case, playing = total stupidityThis whole frozen pitch is the same as a baked hard pitch is a myth. Wear studs or mouldies on a frozen pitch and you'll be like bambi on ice, wear mouldies or even astro boots on a rock hard summer pitch and you'll be fine. Firmness is a lot different to ability to grip, and if we took the firm pitch as being dangerous approach no games would ever be played on 3G.
In recent weeks, I've seen results posted for games in my youth league, played on concrete ground, yet assigned a qualified ref. These L7's can only be doing it for the money
