SDMBA worked with the city of San Diego to create a fun trail that is also more sustainable than the old scars that were there before. It has berm features with some with paver bricks added for erosion control. Also has some rock gardens and small rolly-jump features.

Trail is complete and ride-able. While not officially a downhill directional trail, be aware that most riders take the fire road up and descend on Black Widow. Ride with care in case anyone is coming uphill and avoid riding in wet conditions.
