Lowes: 12-Light Edison-Style String Lights. Could string across the outer edge of the patio and turn on only when need. Would be able to plug in the same outlet as pond pump. Patio is 30' wide, so we'd need to use ~3' of wire or clothesline type rope on either end? If I get an arbor afore center path walk thru, could drape to that?
Water pump. We had one in the backyard at Packwood. I did plenty of pumping but don't exactly remember why. Cleaning stuff. Watering plants. The water was so rusty that it was light brown sometimes yellow in color.
