I don't know about the rest of you nerds, but I had every Calvin and Hobbes book when I was a kid, and I was pumped as heck to get the hardcover box set. You know, the one that weighs like 50 pounds.
So I was wandering through Ghostlands yesterday, and I was wondering, why can't I fly there? Did Blizzard redesign all of the old world except for the old-world BC areas? Being forced to ride at 100% speed is really annoying.
Ghostlands is technically part of the Outland map set (530, where Kalimdor is 0 and Eastern Kingdoms is 1), along with the other BC starting areas. It just doesn't appear that any BC content was touched, probably due to time constraints. Silvermoon City and the Exodar likely weren't meant to be flown in or around, though I can't speak for Blizzard.
