Okay, I made my share of complaints about this country. and Believe you me, you haven't even seen a tinkle of the whole sea of complaints I had.
Whichever the case, the good thing about the Netherlands, which is not to say is the only good thing, nor is this a characteristic only the Netherlands has.. but forget this not to sidetrack and moving on.. is that it has hell of a lot of festivals.
I mean I don't know all of it but let me just give you a list of some of them.
