Slideshow Stumped

I've been having some trouble with this assignment in deciding on a person to profile that is related to my beat.  I'm not really sure who I could talk to that would be good for two minutes of airtime, especially one that would be considered somewhat of an "expert" on the subject.  I'm a little worried; any suggestions would be appreciated.  

I had thought about possibly interviewing the owner of a skate park, as it is a popular, fun activity that is inexpensive to do, and there would be a lot to photograph as well as people to talk to.
