I will certainly write here after few years in US and if I get opportunities to visit Europe. For now, I just want to say that everyone who has expressed their +ve or -ve view on US does not apply to every part of US. Its difficult to generalize the life style of US. Here you always have options to choose one way or other. If you are in dilemma to choose one city or other in US you will remain the same even after you choose one. You never run out of option.
