Passed through the Humphrey terminal in September last year.
Immigration were very polite & friendly but very thorough in their questioning.
The most thorough i have ever experienced on any trip to the US.
Kept on repeating the same questions over & over.
I think they could not believe that anyone would choose to come to MN on holiday without having relatives out there.
Had a bit of a grilling going back to the UK but i look on it as better to be safe than sorry and if 10 mins grilling of a couple of middle aged English tourists will help future immigration controls then i'm all for it.
