More to the point, what does the frost line have to do with buried wire,
anyway? If you don't bury radials that deep, why would you have to do so
with a perimeter ground wire? For that matter, all of my feed and control
lines come across the lawn in two runs of PVC conduit, which is buried only
about 3 inches deep, and it has stayed put so far through one very hard
winter and two average ones.
Am I missing something?
