WOW: Catch Cata fish/Volatile Water

This exploit allows you to fish in the Twilight Highlands without all the hassle of getting around No Mands Land.
Go to the river in Wetland at the side of Arathi Highlands and go (on the side of Arathi) past the coast of Wetlands. Now go to the north of TH and go fish. You won't see the message that you're in the Twilight Highlands but your fishing bobber will be.
