Pine trees can hold their needles for 2-5 or more years, depending on the species. Spruce trees generally hold onto their needles longer than pine trees do, approximately 5-7 years. One evergreen tree that is very noticeable as it loses its leaves in fall is Eastern White Pine.
Razorfen Downs is located in the Barrens far to the south. It is in very near the border to Thousand Needles and along the Eastern edge. It is a mid-size instance for both Alliance and Horde players, although it is located in Horde territory.
I have played a lot of the courses in the D.C. metro area, and have never been satisfied with an entire course. A few holes from each course, yes, but never an entire 18 holes. With the new TPC Potomac at Avenel Farm I was captivated from the practice facility before our round to the draft beer at the end of our round. I attended a few of the PGA events held here (Kemper Open, Booz Allen Classic) and heard all the gripes from PGA Tour players, but obviously never experience them for myself.
