One thing I like about the UK is that it's really not very big. If pushed, I could walk from one end to the other in a month or two. I'd pass a town or at least a village every day so I wouldn't starve either. Side to side is, in most parts, a week at most and that's not even rushing. The thin bit, between Glasgow (West coast) and Edinburgh (East coast) is around 50 miles. Two days walking with lots of rest stops.
Not so America. That place is huge. Unlike the UK, it has desert regions where walking would present a very real risk of death. It has massive areas of woodland where you could get lost, die, and never be found. There, you'd have to have transport.
But at what cost? If this is to be believed, flying will soon be dependent on allowing yourself to be fitted with a zap-o-matic wrist band. I don't like the sound of that.
I also don't like the thought that such ideas don't take too long to cross the Atlantic these days.
Fortunately, I don't like flying either.
