At last, the rain has come!

It has been what seems like ages since we have had a decent rainfall grace our neighbourhood. We've just recently had the ash tree stump left from last spring's tornado gound to mulch and a couple other volunteer trees removed as well. The rain quenching our dry lawn is icing on the yard work cake! We're also taking advantage of the rain and collecting some for watering plants.
Rain has a mysterious quality (at least to me) the rejuvinates the spirit and inspires creativity. I wonder if there is any scientific phenomena at work with air pressure, temperature chage, or whatever that is quantfiable in a way that might influence people emotionally, psycologicly, chemically or otherwise. I always feel most creative during rainfall. Maybe I should go grab a pen...
