FWIW - us Yanks aren't fond of TSA, Homeland Security, CB&I, but I was trying to focus on why people might visit or want to visit the US & not send the thread to the TSA forum

.
And while some states have a 55mph limit, others don't - or folk don't follow it

But yes, it was enacted back during the last big oil crisis. Granted we all don't go as fast as folk do on the Autobahn, but there are certain places (the Great Plains states) where you'll be left in the dust if you do the speed limit. Actually the state I live now everyone speeds, but they're very polite about it. They pass quickly on the left & then immediately return to the right lane; the left being left free for passing.
And yup - our weather can indeed be big. Heck, I just saw a pic from Arizona a couple of days ago where a dust storm kicked up that lasted 5 hours & was 50 miles wide
But to summarize what I said before - there's something for everyone, whether it be culture, nature, food, weather. Keep other places on your list, but visit the US too. We like visitors - especially FT ones.
Cheers.
