whats this?

There I was on my way back from a failed Blip attempt at the local bike and skate park, due to the large volume of neds hanging about trying to get into my photos, when I noticed a small track leading off from the main road that I had never seen before.

I went to investigate and found a short but fun piece of single track, after a couple of runs through it (conscious I wasn't wearing my helmet) I set up the tripod and tried to capture the fun.
