I live south of Boston- the Tedeshi's convenience stores are EVERYWHERE! And WAAF is a rock format station which is the most popular in the local market, WEEI- is a sports- talk radio station that has that market completely wrapped up as well.
All we need now is for some athlete to drop a tweet about Phase III.
Here's a nice link that discusses both stations. #1 & #2 rated shows in the market. If we're advertising on these two stations- it is as targeted as you can get.
