Maybe it is the middle of July in Montana (instead of Georgia) and both you and your tomatoes are wilting in your yard, both looking to the sky and hoping for rain.
Or maybe a low-pressure cell has been napping overhead and your arm is hurting from holding that umbrella while you watch your basement fill up with water.
Either way, you would like to know how much rain has fallen–how many gallons have come down from the skies onto your roof, yard, block, or town.

Here’s a sample:
|Your entries||Amount of water that fell|
