went to Gladwin, MI over the weekend to ride with some friends. Wish I had more video but my battery died... I was using the GoPro Hero 3 + black edition. I was riding on a 2015 Yamaha raptor with a two brothers exhaust, fuel manager, and open air box K&N filter. My friends where on two new 2015 ktm's. one was a 300 2-stroke and the other was a 500 4-stroke. It was about 45 degrees when we we're riding
