I've been known to drive around the nite before trash day looking for heavy cardboard boxes. I'm always thrilled when I find the person who got new appliances. With the nasty weeds we have in FL, smothering them with cardboard is about the only way to smother/kill them.
I'm in the process of re-doing the back yard. Guess I should take some before pics so I can remember how overgrown & lacking grass it is!!!!! I'm hoping it looks much better this time next year.
