Speed of electricity (186,000 mps?) is quicker than a blink of the eye.
I guess Texas is not just good, but lucky, too.

I thought that was the speed of light and that electricity took the local "bus"

Mick was actually pretty accurate. The speed of light is approx. 186,000mps, but they have electrical pulses that approach that speed now.

I couldn't get your link to work but Mick's answer is incomplete. The speed of light is 186,000 mps (about 1 ft per second) through a vacuum. Electrical signals do not travel through a vacuum, they travel through conductors that are surrounded by insulators (dielectric). In the most commonly used cicuit boards signals propogate at about one half that speed, .5 ft per second which is the same way as saying it takes 2 additional nanoseconds for the signal to travel for every foot of conductor on a reasonably manufactured circuit board. It's much slower per foot if we're talking about cables surrounded by air, which is what we're talking about when we connect a control board to a horn, scoreboard and lights in a basketball arena.
