You think stubbing your toe on the coffee table in the middle of the night sucks, try whacking it on a sandstone garden fountain. I know they say that beauty is pain, but I'm pretty sure they meant something more along the lines of waxing your upper lip or, well, all those other weird things women do to look pretty.
Unless you live in one of those weird places in the northern hemisphere where it never gets dark, there are just not enough hours in the day to appreciate the aesthetic appeal that a fountain can bring to your garden. So when the sun goes down, turn those lights up. After all, class doesn't have a curfew.
