2. What are the neighbors like?

my thought also, there are none for 1/2 mile here, i've also learned this is direct burial, and old (30 yrs) too, just to add to any theories anyone might have here.

i managed to fanagel the inspector there today.

he felt i should bond everything, which i am now doing, then go looking for the same problems i'm quackin' about here.

i had it in mind anyways....

maybe i can get a pix of that x-former here, that %$#! digital is smarter than i.....
