I had WUFC-AM 1510's streaming audio on this afternoon while I did other things from 3:00 pm until 6:00 pm. That's the only local call-in show weekdays on the station. I've been led to believe that there's some activity going on in the sports world involving Boston franchises. Yet, despite constant pleas for people to call in and frequent repetition of the phone number, they got ONE and only ONE caller during that period.
