Is there an easy way to find Physician Assistants to shadow?

I have difficulty finding PAs when i search online and do not really want to drive all over town trying to find where they work. I have found a site that lists the PAs in the area but says "general medicine" for all of them when i know for a fact that at least one works in dermatology. i really want to find some PAs in pediatric surgery or other fields of surgery to shadow. any suggestions would be great! i know that i might just have to suck it up and go office to office before finding someone.
