Hi Marcel,
first and maybe most important question, are you a club or a school guy?
If you get along with the dependencies and caveats in a club, you can trade money for being part of a klubben, but you have to like it. Sharing interest in airmenship in the boundaries of a club may save substantial money by having buddies introduce and train you. I.e. I am a school guy, I need to get myself and brain independent of socializing pressure into club structures.
Stroll around Roskilde, but also at flyvepladse nearby like Avedøre, Ølstykke, Fredtoftegård, or even on the swedish side Vellinge and Fridhem Gaard are worth getting people to know.
