Nyxondra's Broodling are a great source of Thick Leather. There are tons of the broodlings confined to a small area and the re-spawn rate is high. By the time you farm from one end to the other, the side you started from has re-spawned.
In a one hour farm I bagged 10 stack's of Thick Leather, 2 stack's of Rugged Leather, 6 Thick Hide and 5 Green magic items. This should yield close to 250 wow gold on my server.
