Gordon - I agree that night lights in the garden are a must. I have been VERY tempted to get some of those solar tiny christmas string of lights. In fact, they now sell them as outdoor lights. A string of them would look nice on one of my arbors!
Please, if you could, take a flash photo of your favorite outdoor lights and tell us who makes it and where you got them. And I do look forward to more night shots with your Nikon camera!
