In reply to Xharlie:
I travel to the US 2-4 times a year for work, mostly to Philadelphia but sometimes to Baltimore, Boston or NYC, and often take the opportunity to visit other parts of the USA while I am there. I have never even thought to ask for incentives, but then again I don't ask for incentives when I go to Malawi for work either...
While you hear horror stories about TSA and travel, in reality I have always been able to carry devices with me (from the UK at least) - I generally travel for work with a phone, Kindle, tablet and laptop in my bag - and I have never had any of them screened. I have also never been searched in any other way, and while TSA staff can be somewhat brusque none of them have ever been anything other than professional towards me. Of course, I am white and travelling from a country that the US generally perceives as non-threatening so other people may have different experiences - however as with any travel, it is the occasional horror stories that hit the news and not the thousands of travellers every day who have no trouble at all.
As for the food - of course you can gorge on obscenely coloured high-fructose corn syrup laden crap easily if you like. You can also get a wider variety of high quality food in restaurants for a lower cost than you can here. The best meals I have had out within the price I can afford have all been in the US.
Yes, the political situation sucks, but so does ours...and just like the situation here, some people agree with what is going on and some are very opposed.
The US has some fantastic wild places, and some fun beautiful cities with interesting people in them. It is a strange place - it has a culture that is quite different to the UK, but for me experiencing that in any country is part of the fun of travelling - to miss all that because of some perceived issues that probably aren't ever going to affect you seems like a very closed attitude to me.
