Maastricht... off-topic, but last year I listened to a group of people who spoke a presumably German dialect I never heard before, it sounded a lot similar to K�lsch (the dialect in Cologne). Finally I asked them where they were from: Maastricht! I was really surprised, it didn't sound like the normal Dutch at all. This shows what I learned in linguistics: originally, there was no clear language 'border' between lower German and Dutch dialects, but a continuum of step-by-step changes every few kilometers.
