One time my friend and I were in the mountains near Lake Louise, we were planning on camping in the forest. It was a nice sunny day in September and we decided that we shouldn’t spend such a nice day in our tents stuck at some campground. So we decided to go into town and rent some mountain bikes and spend the day ridding. So we hopped into my friend’s car and drove to a sporting goods store in town. We then found two good bikes for rent at a decent price, we hitched them up to the back of my friend’s car and drove to the nearest trailhead. Once we got there we unload the bikes and started the steep up hill climb over the roots and rocks. After about an hour and a half of climbing we reached the top of the trail. Then my friend had either the best ride ever or the dumbest idea ever. He suggested that we race done the trail back to the parking lot. I agreed and we sett off down the trail riding as fast as we could. The trees and rocks that we were passing were just a blur of green and gray. Then with out warning my friend caught his front tire on a root and was flung head first over his handle bars, he flew through the air before crashing onto the ground twenty feet away narrowly missing cracking his back on a tree. I watched in horror before jumping off my bike and sprinting over to him to see if he was all right. I kneeled down next to him and asked if he was ok. He wasn’t ok, his left shoulder had been dislocated. Luckily we were only about twenty feet from the parking lot. So I walked the bikes to the car and attached them while my friend got into the passenger seat. I drove him as fast as I could to the hospital, where we waited for about an hour to see a doctor. The doctor promptly popped my friend’s arm back into his socket and sent us away. Once we got back to our campsite we made a fire and thought about our day and how stupid it was to ride down the trail as fast as we could. We both agreed that we should never try to race down a trail again.
