macnugget good, job! Everyone has good ideas. I have been tossing around ideas but nothing solid yet. Auto-waterers have drawbacks in freezing weather. At least mine has the water lines freeze and bust. I have to tilt my water containers to leak slowly to keep the water lines running and not to freeze. I've tried buring the lines and covering the lines in 3/4" conveyor belts. Well i rambeling i'm just letting u know what my experinces have been with outdoor situations.
