I got a few 'Raw Fine Hides' from parking myself between the two Treants in South Karana (NE corner of the zone LOC:+1500, -3700). I got three fine hides and four supple hides in about an hour. Other places are certainly faster, but this is certainly the most brainless. The treants will automatically attack anyone of any level if you have bad faction with them (which would be any evil race), and they have a fairly short spawn time (3 minutes). You can watch a movie, do your taxes, eat panini sandwiches, etc. to your hearts content and just let the hides just roll in.
I would suggest that only evil races try this, since there are some faction hits:
-Jaggedpine Treefolk
-Protectors of Pine
-QRG Protected Animals
-Guards of Qeynos
+Unkempt Druids
