Irondequoit Bay Park West Mountain Biking 6/16/12 

Looks like he started at one of the purple trail heads and merged onto the blue trail, then orange and so on. You can see the colored tags on the trees in the video.

Trails are purple to blue, then orange, red, blue again then green.

Where did you start at? Just bought a mountain bike and I really want to go there when summer comes.
