I have started a game called Tesla Supercharger Treasure Hunt. This is intended to be a fun thing for the Tesla community to participate in while they have time to kill at Superchargers. I have setup a website that is not commercial in nature and contains details. You do not have to join the site to participate unless you want to. If you want me to post a hunt you are setting up just contact me through the contact form, no membership required. One hunt has already been completed and you can get the idea from how it works by reading the details. Next hunt will start in a few days.
