This years light count is 23092 and just a few leds/incandascents on the spiral trees.

1000s upon 1000s of feet of Cat5 cable is used to hook everything up

It takes 18 days to put up and hookup all the lights (split between October and November)

And about 3 or 4 days to take down and store them all. 

The electric bill is not as much as you would think.  My December bill is about $20 more than my November bill. Which is much better than the $250 bill I would get when the lights were always on and not LED.
