Today i did some mountain biking with a few riding buddies. We were heading down a fire road and we saw a white truck parked facing away from us. The water department trucks are orange so we figured it was an undercover patrol. We turned around and headed down a tight trail. At the bottom there is two large cement blocks that have been there for years. There is a small berm around them that everyone goes through. I was in the lead going about 8-10 mph. I entered the berm and got about half way through then WHAM. Something hooked up on the back of the bike. I got thrown into the bars and then the bike started to pivot into the blocks. I rolled myself over the bars and hit the ground. I got up to take a look at what i snagged. I was shocked, it was a piece of barb wire anchored to the ground in front of the blocks. The last barb hooked the corner of my pedal destroying it. The wire was looped through the berm. It was definately there to snag a peg or some other part. If i ever find out who did that they will pay. Im going back tonight to see if there is anythhing else on the trails so someone dosent get there neck broken.
