Very interesting Derek. Funny, I had this vision as I was reading your post...
Some guys are birdwatchers, they sit watching out for a pale headed brush finch.
Some guys are trainspotters, they stand on bridges waiting for a steam train to arrive.

What do we do? We sit about watching to see if there are any other kilt wearers in town
Does that make us kiltspotters or kiltwatchers?

You make Wales sound like the place to be in a kilt, well done. Swansea is a lovely area, I would imagine it would be the place in Wales for a kilt revival to happen.
(I remember another lovely town, I think it was called Betsy Coed. ??)
