There are quite a few people on the board from around the country (and world for that matter.)....so I thought I would share the links to the local Chicago Sports Talk Radio stations. They have live internet feeds on each of them.
This isn't all sports, but every weeknight from 7pm-9pm CT, there is a good show called Sports Central on hosted by David Kaplan. This is the Cubs flagship station.
670 THE SCORE
The Score is actually the White Sox flagship, but they do talk about the Cubs quite a bit and have lots of live interviews with the players and coaches.
