A cistern holds water that is diverted off the rooftop during rains. How grandma and grandpa raised 10 kids with just rainwater, I'll never know. Maybe at some point prior, they had a well (at a different house?) Anyway, not too long before my grandmother went into a nursing home, she got indoor plumbing, woo-hoo!! I remember being attacked once by a nasty rooster on my way to the outhouse; the next day, grandma put him on the chopping block. One of my dad's surviving brothers lives there now, alone, and only leaves the house to step onto the front porch to get a piece of wood for the stove. Grandpa died in '67, grandma in '90.
Keely - you're right. I watched the bucket fill today, and the valve needs to be closed a bit. We've got condensation on the windows; between that and my sinuses, I know we're humid enough.
thanks
