Mower deck, without motor but WITH wheels
Crushed washing machine
and lots of rocks
Don't feel too bad. The people that lived on the land I now occupy were slobs, too. I have lived here 16 years and the glass keeps coming up. I usually see something shining and carefully pick it up and put in in a bucket I keep for just such things. I think the culture of the people is slowly changing. I have noticed the glass being replaced with fast food wrappers and plastics. They degrade in only one lifetime. Did you know the State Insect of South Carolina is the Litter Bug?
What you need is a bottle deposit law like Michigan. Before the law, cans and bottles all over. After, nothing. If someone throws one out, somebody else will pick it up for the .10 deposit.
here is a problem for ya.I saw a show a while ago, a biography of Charles Darwin, before evolution he was famous for a study he did on earthworms. He stated that part of the reason that some objects rose and some sank was the action of earthworms doing thier thing tilling and generally moving the soil upwards.
Stupid little factoid.
My land was a farm 80 yrs ago and I pretty sure the farmer grew rocks and now they gone wild.
