Excuse me if this has been noted.
I was exploring, after hearing that it was possible to fly into Old Ironforge (yes, I believe things very easily), so I was looking around for a tunnel, which I assumed would most probably be the best bet of getting into a cave. So I flew up to the Airport to check out the Tunnel that was up there when I went exploring pre-Cata, and I found this:

Please use that link, I haven't used Imgur in ages, so I can't figure out how to reduce the image sizes. I don't wanna be destroying no monitors today.
For those who don't trust it, there is a gate covering the previously open tunnel that lead up the mountain, only to reach (iirc) a wall of snow. But now, there is a gate covering the tunnel, consisting of vertical bars, spaced enough for you to see the tunnel, but unfortunately, not the end of the tunnel, and the Wildhammer symbol in the centre.
Discuss.
