Re: Heat Tape on garden hose.
Well, I can't give any advice on a hose, but next summer you should run a buried water line out to your water trough and put in a freeze-proof hydrant. While you're at it, run a 120V 20A circuit out there for a tank heater. Better yet, just get one of these: http://www.ritchiefount.com/productsEQUINE.html
