USA. It's the country I have visited the most times (20+ holidays from the UK) but would not wish to live there. Maybe I've watched too much TV but the gun culture is frightening. Once when entering the Beach Club car park, after showing my UK driving licence as ID, the security guard said 'Is it true your police don't carry guns?', I said that was true, and he just shook his head in absolute amazement
(PS This is not meant to offend or start an anti-gun conversation or the reverse, it's just my answer to the thread's question)
