THe Lincs Wolds are very strange. Like the Gobi desert. You ride along this B road for ages, hundreds of feet up, and you see no villages or pub or shops. The road has a name but I can't remember what. It's an ancient drovers' route or something. And you notice that when you are in N. Lincs, everyone speaks with a Yorkshire-ish accent. When you are S. Lincs, everyone speaks as though they are from Norfolk. That proves that the Lincs Wolds were put there to keep the Northerners out.
