      Hey everyone This is a great area to come ride! There are three main places you can ride, a BMX and dirt jump area, a cross country area, and a nice downhill area with tons of jumps.

      Ride this maze of trails just south of the Seatac airport. Lots of fun riding through an area that long ago used to be a neighborhood. Plenty of winding trails to spin around on and the low flying jets keep thing interesting. Trails exist on both the east and west side of the SCORE jail access road. It's fairly flat and beginner-friendly on the east side of the access road; west side trails have are more advanced with more hills, berms and jumps. West side trails are accessible through gates in the chain link fence along the jail access road.

      Overall its a nice area, lots to do tons of lines!!!!
