Meet Caleb.

He's an SDSU student from Pierre, South Dakota, who's something of a historian on all things Hobo Day. (Well, the buttons at least.) When he's not rope-swinging or playing some tunes on the guitar in front of a campfire, Caleb is putting his SDSU experience to good use.

Thanks to the opportunities available in his area of study, Caleb has been able to work on undergrad research, including the chance to synthesize anti-cancer drugs during his sophomore year. It's all part of his feeling that, "Because of SDSU I can go out into the world and leave it better than I found it."

Check out Caleb's story in the video above.
