Duncan,
I've not played Tenby, so I went to have a look on Google maps and as I panned around looking at an interesting routing of 18 holes through what appeared to be dunes, I was wondering what you and the others were on about? I then noticed the 3 holes on the other side of the railway and with a bit of work, I figure that the hole you show above used to be the first, but due to its proximity to the clubhouse (ie blocked and sliced approaches probably hitting the clubhouse and its surrounds) they appear to have rerouted and closed a few holes (current 8th was previously 2 holes and there was a par 3 between the current 9th and 10th holes?) to make what I guess was the old 2nd into the first and added the 3 holes on what you say is the not so links like land on the other side of the railway. Bing maps shows the course a little more like it is today I believe?
Anyone throw any more light on the history?
Cheers,
James
