I walk around the countryside a lot but rarely clothes-free. The problem I have is with the vegetation which tends to be either prickly

or to harbour ticks.
I love walking naked along the water line at Morfa Dyffryn beach, especially at low tide. There is a wonderful sense of wide open space and the mountains make a huge amphitheatre beyond the dunes. It's the opposite of our usual venues where we have to lurk behind high hedges and curtains.
I am also a bit more wary about meeting people who may be surprised or even frightened to see me where they wouldn't expect it. It may not be illegal as such but I could do without the hassle of convincing the police or a magistrate of that.
