I refuse to poon in the USA. for one thing it is illegal, and if you get caught up in a police sting, you will be kicked out of the USA for quite a long time, maybe forever. A very bad thing if you do business there. Some others have gone there and done well, and reported back to PERB favourably, you should be able to find those posts in a search.
It is a serious threat, this LE action. I would not flirt with it. Have taken an sp with me across the border just to avoid the issue on a few occassions, much safer to take the right one. But you have to be careful there too, like get one than knows she can get across ok, and don't buy her ticket yourself.
