Environmentalists are once again grappling with small business owners around Yellowstone National Park’s gateway communities over the issue of riding snowmobiles on park grounds.

According to snowmobile advocates, the current winter use plan, which caps snowmobile use in the park at 318 machines per day, will devastate local economies. But some environmentalists, like Coalition of National Park Service Retirees spokesman Bill Wade, argue that Yellowstone officials have already “compromised both sound science and public policy” by allowing the noisy, air-polluting machines into the park in the first place.

But all social issues aside, snowmobiles are fast, powerful vehicles that can be dangerous as hell. Combine that with fearless drivers and you’ve got the makings for some epic wipeout footage. As usual, you are about to witness some pretty gruesome carnage. Heads are crushed and bodies fall off unbelievable precipices. Here at Wend HQ we love a good wipeout, but we’re not morbid. No matter how brutal these crashes are, everybody in the videos lives to ride again.

Consider yourself warned.

From William: (There’s an old saying in Tennessee — I know it’s in Texas, probably in Tennessee — that says, crash once, shame on — shame on you. Crash twice — you can’t get hurt again…)
