If your horde then yes you should get a quest from one of the trainer[]s[/] i don know where becasue im alliance and alliance dosnet get a quest for a leather 6 slot bag for newbs
once again the nerf hammer has smittin the alliance
My understanding is that Blizzard added a 6 slot leather bag to the tauren area because the tauren race does not have any cloth wearing classes (Druid, Hunter, Shaman, Warrior) so they are unlikely to take up tailoring. The kodo bag gives low level taurens access to a six slot bag.
