One design I got to look over was about a 200' signal ground cable 
grounding racks that were right next to a microwave tower and were going 
to contain the microwave equipment. That got changed really fast. I'm 
glad I scanned the drawings...it wasn't my project.

The other nasty I had was the connection to my old overhead service 
entrance was supposed to be disconnected by the power company. I started 
pulling it out and had lots of sparks and had to dump a fire 
extinguisher into the brush. I don't think I've ever cursed more at a 
public servant...and he said I was right to have done that. He was very 
embarrassed.  I survived and no major damage happened. The truck was out 
in less than 20 minutes and the cable was then disconnected.

Cheers,

Richard
