I was wondering how all ya'll do you water over the winter. I keep a 3500 gallon tank by the fence and let water out of that into a 50 gallon tub whenever needed. To keep the tank from freezing in the winter, I insulate it with hay bales and keep a heater in it. For the valve, I have an insulated box with a heat lamp inside. This doesn't work quite perfect, so I was wanting to glean ideas from you guys!
