I can honestly say my horse barn is totally off the grid. I have finished rigging the gutters to fill water troughs with rain water. That is ugly 4" drain pipe hanging across the barn door opening hooking the gutter downspout to the water troughs. The first trough is pitched to drain into the second one. Initially, I tossed a third trough under the gutter downspout on the other side of the barn. That sucker has been kept full with the rains we have had. I went ahead and rigged up this contraption at the front of the barn. Now I'll have to haul water less often so long as we get some rain. There is also a small pond I have given the horses access to so that will help me maintain my lazy lifestyle. The black square sitting on top of the roof is the solar panel for the lights. Since I have went back to my natural hair color (mostly gray) and done all this at my barn, I feel like a freakin' hippie. If I quit shaving my pits, feel free to smack me upside the head.
