It's just the honor system. No one steals stuff (knock knock). If you want to feel safer about it, buy a small pop up tent from Amazon and keep stuff in there and close up before heading to the track. The tent will also keep your stuff safe from the elements of sun heat, rain, etc. as well, very handy.
