I live on a corner lot. On the corner on the street, people like to drive over the curb and the yard as they go around the corner. I put some pics here for those that want to see exactly what is happening:
When the weather warms up I am going to do some cement work, including replacing the curb you see in the above pic. I need to do something to discourage people from driving over the curb and destroying it, plus I'd like to get grass to grow in the corner where you see mud. I've thought of railroad ties, rocks, bricks - it needs to be big enough so that they won't just drive over it, and strong enough so that if they do drive over it, it won't damage it but will get their attention. If it damages their truck of if they get stuck, it won't break my heart - I can't tell you how many times I've thought of putting nails in the mud, but I won't stoop that far.
Any suggestions? Anyone been in a similar situation and would like to share your experiences?
