When is an inch more than just an inch?

When that inch is on your neighbor's property! Ever since moving into our house our dog has been wreaking havoc on the neighbors, mailman, meter reader, other animals, etc... You get the idea. Last summer we built a fence on either side of our house preventing her from scaring off the mailman, meter reader and kids in the culdi sac. This spring our project was to fence off the remaining portion along the back of our yard. The posts were dug and set two weeks ago, only to soon be followed by a neighbor we had never seen or met before to be out there digging a hole. Long story short, our fence posts are on our neighbors' land -- in fact, two neighbors...lucky us. Out of 17 poles, we are moving 7 - each about six inches from where they currently sit. We can't be angry with the neighbors because it was our own screw up, but perhaps what is most frustrating (other than our own stupidity) is that we're talking INCHES, but yet hundreds of dollars at the same time. Actually thousands of dollars of total fence cost. Honestly, I'm tired of thinking about it, talking about it and dealing with it and we're coming down the home stretch now. Unless something goes awry this may be the last I speak of it...ever! Word to the wise, if you want to build a fence, ask the oldest neighbor you can find where the boundary markers are...chances are he'll know.
