Larry has a little disc that you can’t really use as a frisbee (although it would fly) that is meant to be used as a marker for your foot so you can pick up the disc that you threw. Let me back up, first you throw a disc. Then you place one foot on the spot where that disc landed and throw the next disc. If you want to throw the same disc again, you need to pick it up, so you have to put down a marker to ‘mark’ your spot. And Larry has one. Because he’s serious about this stuff.
