Used to have a lot of that in south Arkansas.........used the conduit trick more than once, unless it ran thru a bunch of trees!!!
Replaced a span of 1/0-3 secondary one day to cure a squirrel problem.....2 weeks later, the dang tree rat had chewed thru the dang neutral again......this was after the company quit buying cable with the 7/1 neutral and was just buying the dang AAAC neutral........
kinda broke spec and ran a single 1/0ACSR for the neutral and patched the AAC neutral up.........
their loss, my gain.....job security........
