Sam,
You were pretty much spot on about DCC. However, you really must have botched a shot to go OB on the 3rd hole. It is only about 120 yards from the tips, with a huge bunker complex to the left, and then another ten yards or so of space before you get to the OB fence. I play out at DCC a few times a week and I still am yet to post a great score. It is Par 71 and about 6300 from the tips, and my best score is a 69 (I play to a 0-1 index). When you look at it on the scorecard it should be a cakewalk.
It is extremely narrow and it also uses turtle creek to help extend some length. The creek cuts through holes 4,5, and 8 on the front nine and forces the play to lay up off the tee. The fourth is a par 5 that require an 3 wood or for a longer hitter an iron of the tee. The fifth hole is a par four but requires about the exact same distance lay-up, forcing about 160-180 to the green depending on how frisky you want to get with the water.
The 11th hole is a fun short par 5 with a cool bunkering scheme and the downtown Dallas skyline directly in the distance. Between the 11th, 12th, and 13th holes I don't know if there is a stretch of golf anywhere in the world where more cars can be hit by golf balls. Preston Rd (to the right of 11) and Hillcrest Rd (to the right of 12) are always packed with cars and there are usually a few problems a day with cars being hit.
All in all, DCC is an extremely good golf course considering what they have to work with. I personally would prefer Claremont as it is much more unique and has a much more interesting piece of property.
