Weed control.

The weeds in the back yard have gotten out of control. Today me and the family went out back and were pulling weeds. After about an hour we hurt and had only accomplished about 1/4 of the job. I have decided to go to the Home Depot tomorrow and buy Weed Killer for the rock's and Turf Builder for the grass. If any body has a better plan that will save my back I'm willing to listen.
