That's the stuff I was talking about...corrugated plastic tubing,
maybe 1.5" diameter. Very tough stuff. I can't imagine it being very
expensive, though I've never bought it. The last time I ran
underground conduit (the infamous "fart conduit") my friends and I used
a big spool of stuff that we bought from Home Despot. It worked great.
It was maybe 120' long and about 3" in diameter.

Shit yeah. And lots of induced voltage from even not-so-nearby
lightning strikes. I hate to say this, but Greg is 100% correct
here...shield grounding and isolation are *very* important for long
[conductive] cable runs.
