Nope never been across the pond.
I am looking to make the move sometime in August at the latest, it may be earlier, or (gulp) not at all, as we continue to go through the machinations with HR and UK vs. US management.
And I am GREATLY looking forward to it, I am from Jamaica so I think I actually have a leg up on the average American when it comes to what to expect over there. We were a British colony for a few hundred years, my aunt/uncle have been and to hear them tell it, the UK is like Jamaica, but colder, and a much more developed infrastructure. We drive on the same side of the road, spell things the same way, and I grew up watching playing cricket/rugby/football as the rest of the world knows it. Even when I read threads about the run around of going about your business it reminds of things I did in Jamaica up until I was 19, even the driver's license process is the same down to putting that big red "L" on a car if a driver with a learner's permit is driving.
When you bring in the fact that Europe and Africa are no further than a flight to Atlanta or Los Angeles away respectively, I am very ready and excited to come across.
