Recycling Water Tank

Farmers & Ranchers were "green" way before it was cool, mostly out of pure necessity, as well as a gut driven desire to make it better than it was when acquired.  Our latest improvement is a water tank at the bull pasture, a farm that has only had pond water for the last 25 years or so.  No more hot, stagnant stuff for our girls, now they have nice cool, clean water.  This cow was the first to drink, and oh, she did enjoy it.  Notice the JUNK and arrow spraypainting, it was ruined at the mine where it was used as a loader tire or something like that, looks better here being beneficial to cows than it would in a dump of junk! 

And ontop of it's "green-ness" it is solar powered.
If it were only heat powered we'd really have it made, only 108 here today. 
PRAY FOR RAIN!
