I will pitch Castletown. Okay, it is on an island, but an easy island to reach. I think folks give it a miss because of the nearby LANCS and Cheshire courses. Of all the courses in this general area Castletown is my favourite. Its not the best, but it is my favourite. I think the best is Formby which itself rides in the shadow of Birkdale, Lytham and Hoylake. In terms of rankings (and my second favourite of the area) Wallasey gets royally screwed. There are countless courses in the GB&I top 100 which aren't as good as Wallasey - Castletown included.
