A bunch of old guys like me meet daily at the same location for a gentle ride. A couple of days ago no one else showed up, so I took the opportunity to take a little tougher ride.
I found myself poised at the top of "Heart Attack Hill" for the last run back into town, so I turned on the GoPro and got an amazing ten minutes of video as the DH trail was empty except for three other mountain bikers on their way up. Check out the "horizon leveling" feature of the GoPro. Even as the bike tips through a banked turn, the landscape stays level.
