Mac -
In terms of quality, and certainly in terms of quantity, golf in England is easily the equal of golf in Scotland and Ireland. Track down a copy of James Finegan's book on English golf courses ("Blasted Heaths and Blessed Greens").
The 75-mile stretch from Liverpool to St. Annes could be the strongest stretch of links golf in the world (Royal Liverpool, West Lancs, Formby, Southport Ainsdale, Royal Birkdale, Royal Lytham St. Anne's, etc.).
The area west/southwest of London could be the best collection of inland courses in the world (Sunningdale, Berkshire, Wentworth, St. George's Hill, Woking, New Zealand, Swinley Forest and many more).
In Kent, there are at least 5 quality links, Royal St. George's, Royal Cinque Ports, Prince's, Rye & Littlestone. In southwest England, St. Endoc, Trevose, West Cornwall, Perranporth, Burnham & Berrow, Westward Ho!, Staunton, etc. are all worth playing.
That just scratches is the surface of what is available. I do not know why golf in England is not more visible to the American golfers.
Maybe some of our English GCA-ers can offer their opinions on that.
