Richmond, Virginia's Wealth of Non-Commercial Radio Choices

A piece yesterday on "The State of Radio" provides an overview of the radio landscape (including commercial, non-commercial, satellite, and HD), specifically in Richmond, Virginia. The most interesting part of the article to me was the final section on non-commercial radio stations in the area. We're given a glimpse at indie-oriented community station WRIR, music-oriented public radio station WNRN and at two college radio stations. According to the piece:

"A couple of years ago, Richmond welcomed WRIR (97.3 FM), also known as Richmond Indie Radio. The station was quickly embraced for its eclectic programming that includes locally produced shows spotlighting music genres such as Cajun, bluegrass, honky-tonk, British oldies, industrial, indie and punk rock, techno and gospel (for a complete lineup, visit www.wrir.org). Also entering the market in 2005 was WNRN (103.1 FM)...The station (www.wnrn.rlc.net), like WRIR, offers alternative listening for genres including modern rock, folk, Celtic, bluegrass, ska and hip-hop. And, of course, college radio stations at University of Richmond (WDCE 90.1 FM) and Virginia Commonwealth University (WVCW, which streams at www.wvcw.org) exist as a training ground for hopeful broadcasters."

Is Richmond unique? Or are there many cities with a wide variety of non-commercial radio options?
