Talking about half-shells..... First run of the day this morning, cruising down greenhorn, and come across a guy knocked out cold face down in the middle of the trail. We hop off our bikes, to render him aid. As he comes to, he rolls over, and half of his lower face is just completely torn off, with chunks of flesh just dangling. Blood is pouring out of his face like a sink faucet. Some dude picked up his teeth off of the trail and put them in his backpack. Luckily, no obvious neck or back injuries. He was in a really tough spot for the EMTs to get him. So we had to escort him up to a ski trail about a hundred yards. He wanted to use his phone to see what his face looked like, but there's no way I was letting him, he would have probably collapsed on the spot. Hope he's able to recover and get back on the bike another day. Please wear full faces while riding Creek.
