Guy calls today asking if I can or would install this underground wire? I ask for what and he says like a dog fence so dogs can't leave the yard. I say sure - I'll take a look. He says well its not for a dog but the same type of wire? Ok - where is this going??? He then tells me how he spent $2300 on a remote controled lawn mower that mows within the confines of the yard where this "dog fencing" is placed. Anyone ever seen this or done this b/f? If so what do you charge for sucha service and what is the best way to install this wire? I think use my side alk edger to make the slit but how do you install the wire without lossing the slit made by the edger - have someone follow right behind??
