So, there are at least 100 stations (AM & FM) that are part of the Yankee or Red Sox Radio Networks - most very small rural stations. In additional, ESPN is doing a National Broadcast of the Yankee/Red Sox playoff game tonight. I thought I would try to catch as many of those AM broadcasts that I could.
Skippy - over/under for totals of first three games: pitchers used 40, total game time 14 hours
