Does your college have a radio station that broadcasts out to the community (not just the campus)? If so, does anyone work as a DJ at their college station? Do you play hippie music on the air?
The University of Hartford (not my college) has a bluegrass show every Sat. I try to catch when possible. I know it is streamed on the net but couldn't figure it out today. The no. on the dial is 91.3 fm. They will throw in a little Jerry and David almost every week. Also 88.1 WESU in Middletown CT (not my college either) has Dead Air every Sunday night 7:30 til 9pm. I loaded their real player thing and that works for me. If you can get the UHART stream the banjos are on fire right now, it goes til 12 or 1 I think.
