Clues

Del Curto Park is in the South Lamar neighborhood. Follow the sidewalk from the parking lot to the footbridge. Cross the bridge and head for the covered pavilion. The concrete steps leading up to the pavilion are terminated on either end by a pile of boulders. Walk to the side nearer the basketball court. Look for the box under the large center rock. It is hidden underneath smaller rocks and leaves.
