re: Grass between pavers/concrete... looks cool but how do you maintain?

I put some big pieces of stone in the ground as a walkway between a patio and my driveway at my last house. Countersunk the stones so they were below ground level so I could just roll right over with the mower. Then would come back with the weed eater and cut back to the edges of the stone. The weed eater part only took a couple of seconds per stone and was real easy. Looked damn sharp. Just had to keep up with it and not let the grass take over.
