From the Amtrak thread:
"I knew a guy who worked for a company that erected high tension towers. As I recall, he said the towers were assembled w/ nuts and bolts, then every joint was secured with a stamped steel "pal-nut" to prevent loosening. Sounds like the "playful elves" have been at it in beer town.
