Well after 17 days, 9 countries (Netherlands, Germany, Denmark, Sweden, Lithuania, Latvia, Estonia, Russia, Finland then back through Sweden, Denmark, Germany and the Netherlands), and 4,531 miles what have I learned?
People are generally helpful no matter where you are. From the members of the bike gangs I met who offered assistance at ports and at the Russian border to the Russian truck driver who stopped to check I was OK and offer assistance when I took a breather on one of the roadworks sections.
Russian drivers are just plain f*@king crazy.
Border officials and customs officers are the same the world over, there must be a special central training school they go to learn how to be so officious and monumentally slow.
Bureaucracy loves paperwork, be it filling endless forms in (some the same as I filled in before) to still registering at hotels. If there is government involvement then somebody will invent a form for it and a civil servant will replace that form with 3 others.
Russian drivers are just plain f*@king crazy. (It is worth saying it twice).
St Petersburg is a great city, as is Turku in Estonia. Finland is also great but you need to sell a kidney to pay for it. Going to the Arctic Circle is a tick in the box.
When you are travelling across several countries try to remember which one you are in, thankfully MasterCard was handy after I tried to pay for food in Denmark with Swedish Kroner.
Sat nav is great to find your hotel but the ride is better when you ignore it.
Would I do it again, you bet your ass I would.
