In case you plan on extending your trip to Northern Europe: hope this does not spoil the fun for ya, but in Nordic countries stealth camping is essentially legal, based on a concept called "everyman's rights". The idea is to camp out of sight, not disturb anyone (including animals, e.g. nesting birds) and leave the place as it was. The exact rules vary from country to country, for Finland see
Finnish Ministry of Environment web site.
