Despite so much hate surrounding them in the beginning, the motorcycle mounts added in Wrath of the Lich King have been a massive hit. They're absurdly expensive, and yet there are tons of them running around. Some people still hate them, but there's plenty of love to go around.
Some of that live hit the official World of Warcraft website recently with a huge gallery of Hog/Chopper screenshots, from both factions. My favorite out of them all is the one I used above, because what's more awesome than Tauren in Lumberjack shirts and silly hats? Not much.
We also posted a little, much smaller gallery of our own quite awhile ago, you may remember. We took the screenshots in the gallery below during the Wrath beta when the motorcycle still had some pretty funny graphical glitches, so check that out too, if the official gallery isn't enough hog for you.
