Delphi Strawberry Service
Delphi Strawberry Service is the cover name for @Camp Half-Blood. They also use this name for transportation. The camp grows strawberries to pay for their expenses. The shell company was founded in the 1930s as a means to help the camp with funding. The idea came from an unnamed son of @Demeter who suggested it at a council meeting.
The campers help pick and grow the strawberries. The satyrs play magical tunes on their reed pipes to increase the strawberry produce. @Dionysus and his children, @Pollux (and @Castor, formerly), use their powers to grow the strawberries as well.
"Delphi Strawberry Service" is printed on the vans the camp uses for quests, or strawberry deliveries. The camp fences have a sign that says: "Pick Your Own Strawberries Please".
