Is that a video on the website? All I get is the sound. The still shot at the start shows a man who looks awesomely fit with lots of muscles all over him. Do you look that good ernie? Will you look that good when you're 58?
For the OP though, go the the states. Most Americans are fairly nice people, they're a lot like brits to be honest and despite the bad publicity, they have a fairly good sense of humour. Yes, there's a lot of stupids out there, the questions you'll get asked when you meet them are astounding like 'where is England?', 'Do all people in England speak English?' and my favourite was 'You have a lovely accent but where did you learn to speak English? You speak it so well.'
