My garden has grass - wild flowers and wild grasses and I can walk in it. Even barefoot (not often, I'm a city boy unused to that). I sometimes walk just to pick up fruit from the couple trees here and there. I'm not even sure what the problem is that requires you concrete in garden, maybe if you need a wheelchair then yes paths might the way to go (I only assume, because I'm not in that situation). Otherwise lawn looks to me barren, a sad splotch of green nothingness. Some neighbours insist on lawns, good for them, even asked me why I don't, and I gave them the above answer. They weren't happy with it as I assume you won't be either, but here I am.

You maybe misunderstood what I meant. I too prefer grass to concrete.

Maybe the entire disagreement in this thread is just between people who think a patch of grass constitutes a lawn, and people who think a lawn is something else?
