A few random additional comments:
1. When in Rome, do as the Romans do. At most UK golf courses the members are not allowed to play off the Medal tees excpet in competitions. How do you think they feel when a group of visitors wangles their way onto the back tees, particularly if they are not capabl;e of playing from back there?
2. Take Tom Doak's advice very seriously. Enjoy the courses you play from wherever you play them. Even if you think you are God's gift to golf, you'll find that the best links courses will expose some part of your game, even if you are hitting wedges into most of the par-4s. Hey, even Matt Ward sort of agrees with us!
3. I've acutally had some opposite experiences, particuarly on some top courses in the US. Some members seem duty bound to push me to the very tips, even to tees which are behind the tips and not yet in play! They think I want to play the full course. Well, not really--somedays yes, somedays no. Even if it is a course I'll only play once in my life, I think I am capable of extrapolating a front tee expereince back to what it would be like from the back tees. If I wanted to. Frankly, even though I am long enough to not embarrass myself from the tips at just about any course, I'd enjoy my game a wee bit forward. 480 yard holes with 230 yard carries off the tee and 200 yard 2nd shots to sloping greens get tiring and boring after a while.
3. Poster Child for middle tees--the Old Course. Nobody on this site will ever play TOC from the tips, unless they qualify for some future Open. If you played from them on a normal day, your line from the 2nd tee would be over the heads of 100 happy people on the Ladies Putting green. On the 14th you would be teeing off from the Eden Course and lucky to make it back onto the real course into the wind. Most visitors play TOC from about 6300 yards. How many come home disappointed?
4. This is all part of a vicious cycle of money and expectations. When one played Pebble Beach for $35 or Turnberry for 7 quid (and neither would let you go to the tips), who really cared? It was just a game of golf and you played by the rules and had fun. Now, when you are forking out nearly $500, somehow "playing the whole course" seems to some to be a god given entitlement. By all means, if you want to play the tips, ask politely if you can, and if you can't, ENJOY! There are a lot worse things in life than playing from the yellow boxes at North Berwick on a fine summer day.
