Rick,
I played Lahinch for the first time in 2013 and that trip was what really spurred my interest in gca. I would say that probably Pine Needles, Cog Hill 4 (pre renovation), or Primland were my favorite. Since that first play we have been fortunate to play a number of great courses in the US and the UK&I. I was quite curious if on our play last month, Lahinch stayed as my favorite. It did. I am not saying that it is the best course I have played. It is that I love the routing through the dunes, the quirk, the green complexes, and the overall experience. Favorite is a fully subjective category, but so is Best.
And if you think that you could live in Lahinch forever, you need to visit North Berwick and Dornoch.
