Okay, so I finally found 6' fence panels at a reasonable price but now I am re-considering doing it myself (or should I say, forcing my husband to do it). Here is the problem; a 6' wood fence needs to have the posts buried 3', which isn't a terribly big deal BUT I have a pretty strong suspicion that a lot of these posts are going to be directly over ledge. Now I know that the fence companies use a rock splitter and set rebar in concrete when they encounter ledge but I am begining to think that this is going to be just too big a job, which is a darn shame because we just can't afford to pay a fence company to do it for us. Is there some kind of tractor-like machine that we could rent that will just pound out the holes regardless of what is in the way? Or is there some kind of sonar ledge detector that could tell me how far down the ledge is? Should I just forget about the stupid fence altogether?
Thanks! Diana
