thanks for all your great ideas, I will look at them all, step by step. But they should help me to find for information I'm looking for (nothing specific, actually).
Two sites about busses that I know off:
, a privately produced web-site about busses in my hometown Bonn, Germany.
, news and reports about was going at German bus transportation companies.
NOTE: Sorry, both sides only in German language.
So thanks again.
