I personally know a man who lives in Bellwood PA. He walks on his lawn atleast once a month with regular golf shoes. The spikes in the golf shoes act as an aeration device. They poke small holes the soil and allow water and oxygen to enter the root system of the grass. Give this a try monthly, or let us aerate your lawn and watch the difference appear in only weeks. You will have a lawn greener than all of your neighbores.
