X In the grass Pets not allowed

Tim says:

Pets do not go IN the grass, they go ON the grass. Much smaller creatures, like snakes or insects, would be found IN the grass.

The structure of the sentence is also a bit strange, and “Pets” shouldn’t be capitalized in the middle of a sentence. Of course “Pets are not allowed” would be more correct, but on a sign that gives instructions, we often skip simple words such as “is”, “are”, and “the”.

O Pets not allowed on grass
