I've discovered two things the US has in common with Russia - neither of them let you fill up with fuel without paying first, and neither of their computer systems at the border can cope with a British registered vehicle.
Whilst waiting to be processed I thought I'd conform to the British stereotype and ask the border guard about the weather. I was told "SIR! I can admit you to the United States of America. What I CANNOT do is give you a weather forecast". I didn't bother with any more small talk after that.
The picture is on the 'Going To The Sun Road' in Glacier National Park. I kept going, I never found the sun.
