Manholes

Ok, I confess. I am fascinated by manholes. When I was in Germany and South Korea I took a lot of pictures of different kinds of manholes, and I've started doing the same here in Norway. There are different kinds of manholes here, but usually some of them have the municipal's coat of arms on them. Wikipedia informs me that it used to be frowned upon, but that it's become an accepted practice. I wish I could take pictures of all the different coat of arms that are found on manholes in Norway, but considering there are 430 municipalities, and that Norway isn't small (in geographical terms at least), it would take considerable time, effort, and money. ^^
