Where you need a permit to do just about everything
As the 1st Ammendment trumps State law then Oregon should lose the case but IANAL (at least in America) and I'm an Engineer (CENG) by education and profession but there is no way in Hell that I'm ever gonna stump up dues to keep my job. That is not a free society.
It is any wonder that the rest of the world looks at the USA and goes 'sheesh?' and they put up with this crap?
Any society that imposes laws like this is doomed to die a long slow death.
