What's funny about Pittsburgh radio stations is that there isn't a single one broadcasting full-time in Spanish, according to these two URLs:
http://www.pbrtv.com/pbrtvfm.html
http://www.pbrtv.com/pbrtvam.html
In fact I can't find any that broadcast in Spanish even part-time.
Draw what conclusions you will about the demographics of the Pittsburgh metro area, and the knowledge that someone living in an area with such demographics would actually have about anything related to illegal aliens.
It's typical for many of those who advocate for illegal aliens to have few that actually live in their own communities or even states. And it also probably explains why so many of them see it as a non-issue.
