I happened to come across this case today: http://en.wikipedia.org/wiki/Wooley_v._Maynard
" George Maynard and his wife, followers of the Jehovah's Witnesses faith, viewed the motto as repugnant to their moral, religious, and political beliefs, and for this reason they covered up the motto [Live Free or Die] on the license plates of their jointly owned family automobiles."
It appears this guy kept getting fined by the local cops for covering up the license plate motto! I'm not from anywhere near NH, and also this happened back in the 1970's, but I never heard of anything like this. Was this an official witness rule? Or was this guy just one of those whack-a-doodles that every congregation has a couple of who make up their own rules that are even more restrictive than the WTS rules, and say it's because they are witnesses? Seems pretty bizarre. Are there other state mottos that are "worldly"? Turns out the Supreme Court said he could cover it up if he wanted without getting fined
