More lights. Need more lights!

Well, I had to work up a rough draft design of how I want the display to look. So off to Target I went and bought up about 4000 lights. But after I got home, I realized that I needed more lights, so I went back the day after Christmas and bought up another 3000 or so. Hey, they were only $1 a box. Best estimation is that the final display will have between 7,000-10,000 lights! Almost all of them will be the mini-light type, so the electrical load shouldn't be that bad....I hope.
