having lived in usa for 25 yrs i was amused by yr ? very little in the usa is "nationalised" unless it comes under a fed law which much of ones life does not. each state has its own driv licence, driv test, tax forms, benefit forms and indeed laws. you could "marry " as 2 gays in one state and be illegal in the next! the country is misnamed...should be dsa....disunited staes of america. dont get me wrong i love living ere but the lack of centralisation is maddening and os wasteful.
