I got a bit carried away today - I had intended to map a short section of road in Pantlasau and then go up near Clydach to fill in some missing roads and names. But I ended up finding an interesting looking footpath and curiosity got the better of me; so I spent the afternoon investigating that path and some tracks leading off it.

In the end I found myself at the *enormous* 275KV Swansea North electricity substation. And it was pretty loud too - you can hear the 50Hz buzz from the transformers a good couple of kilometres away from it. On the way back home I discovered a rather useful footpath crossing some fields to the North of the housing estate, so I can make use of that when I *actually* go up to Clydach to fix up these roads. :)
