I can now confirm the following facts about Belgium (well the Flemish bit anyway);
It is very green (because it rains a lot)
There's always a headwind
There aren't many campsites (compared to France at any rate)
They're a pretty friendly bunch (apart from the campsite owner who wouldn't let us stay there 'cos we hadn't pre booked even though it was only about a third full, but especially the bloke who got in his car a led us to a hard to find campsite near Brussels and the one who gave us a lift to the launderette)
There are loads of bike shops
The beer's blinking great
They really like chips
