Suppose he built a decorative wishing well out of brick (well onto his property) and someone hit it. I don't think they'd have much of a case. Extrapolate. They drive across his lawn and hit his house. What happens then?
The situation I'm referring to: The pole was knocked over enough times that he decided to move the base 4 feet off where the mailbox had to be, actually putting it in his front lawn where it wasn't considered right-of-way. The second time it happened and he complained to the Post Office, they laid it out for him about all the stipulations he had to meet, and when he went to the city, they laid out the idea that he should do the roadside breakaway post and laid out the easement the city had in cases such as the snowplow tearing up his yard or running over his mailbox with a plow (their example, it was spring-ish, so the plow wasn't even an issue, they were simply giving him ideas).
It's why he set it so far back, and he had one long friggen pipe coming from the post holding everything in so that his mailbox would be at the proper place for the mail carrier. He got sued because the idiot that hit his car had to do something similar to what happened in Chad's case - jump the curb and go 4-wheelin'. The post took out the axle of the car, and my cousin was sued because if it hadn't been set up as such, the case was made that the guy's car would still be operational and that my cousin's setup made no differentiation between someone losing control of their car and the "setup" to do damage. His mailbox was run over 4 times in a 3 months by some asshat in his neighborhood, and to this day, I believe my cousin "got" the right guy.
Billf, I've already laid it out for you and your post. Ed is simply pointing out the same thing (although I don't believe he meant to). Note the added the word that SHOULD have gotten your attention -
d-e-c-o-r-a-t-i-v-e. What about that word can't you grasp? What part of "I agree with you, but there's better ways to do it" don't you grasp? What about the concept of 4-5
decorative stones on the edge of his property accomplishing the same thing don't you grasp?
Here. Since you guys can't latch on to the difference between decorative and vengeful, and nobody OTHER than shmokes is arguing the possibility that a purposefully vengeful setup might get their ass sued, I'll point out the idiocy none of you are even CLOSE to talking about with "
decorative walls/birdbaths/planters"

(billf, I hope putting the word in bold AND italics so many times helps you in your quest)
Pant (sic) a nice row of road spikes under the bushes.
Ok then, get you some 5' sections of 4" schedule 40 pipe and a few bags of concrete. Set them bad boys 2' deep in a concrete base and fill em up with concrete. Then plant bushes around them as normal.
Next time this happens, you will know who did it because their plow will still be sitting there when the cops arrive. 
Now billf (and everyone else who isn't getting the difference they might see in court), demonstrate to me how these equate with
DECORATIVE.....the point you can't seem to grasp. Do this because this is the case you'd have to make in court. Regardless of the opinion of shmokes, it's what will have to be done. Knowing that it happened, I can attest to the fact that it's A) NOT a myth, 2) NOT a McD's type of case, and g) NOT a total anomaly that happened somewhere sometime and would almost certainly never happen anywhere else, ever again because it's so incredibly stupid.
And shmokes, if you really think I believed you were saying I did that to Chad's house, you're a bigger dolt than those who can't differentiate between decorative and destructive. The "minoring in math" is because I believe you're trying to have us swallow your tidy summation of such lawsuits based on your statistics that are based on the emissions of your ass.
Your outlook on Chad's "anomalies" are that he's full of crap, yet you,
especially considering that you're looking to become a lawyer, are willing to sweep aside the possibility and probability that such cases can come up, can be argued, and can be won, are wanting everyone to believe that they'll NEVER be won. You're wanting to argue that something that could happen CAN'T happen, and for no more reason than because you simply say so. I'm telling you that "Your honor, shmokes said this can't be won. Move to dismiss" wouldn't have worked in a case I personally know that your views are wrong about.
