A different approach...

Had a revelation this morning on how to clear out the weeds/grass in the backyard. Did some quick research on natural ways to kill weeds and it seems to be vinegar. So my plan is to erect a temporary fence around the area, spray copious amounts of vinegar on the weeds and then cover the entire area with straw. An all natural way to kill them without killing my back :) Off to Home Depot I go!!!!
