Achievement: Fo' Grizzle My Shizzle.
I also completed Explore Grizzly Hills, netting me the Explore Northrend achievement. I got Tabard of the Explorer in my mailbox, as a reward.
If I can finish off Eastern Kingdoms and Kalimdor, I will get both a World Explorer achievement and a title: the Explorer.
Next stop: Zul'Drak. Maybe. It depends on whether I am able to handle those undead mobs in Icecrown now that I am 78. >.<
Whatever happens, I will clear every zone before I am happy. I'm in no hurry to do it; but I will do it.
