What was surprising was the boldness of the thieves. The kiosk attendant was present and there were several maintenance workers close by. Regardless, the thieves slipped out unnoticed.
Placer County Sheriff was called and the crimes were reported. Cameras will be checked and with luck they will catch the criminals.
Be aware that this type of crime usually comes in waves and we most likely will see break ins at other trail heads. Leave nothing of value in your vehicles when hiking or riding.
