New neighbors, front yard and the tire swing

A few weeks ago we hung my old car tire in the front yard tree, and since then our house has become a kids paradise. Three houses down some new neighbors moved in, now their kids are here in the evening and weekends. Across the street the neighbor kids are spending more time at our house then in their yard. It's great for the kids, not so great for my landscaping. Good thing we have lava rock, so five minutes with a broom and we are almost good as new.
