Palins Parents Told To Listen To Radio
Posted by CBS News Ryan Corsaro:
Alaska Governor Sarah Palins parents were called early this morning at their home in Wasilla and told to listen to the radio by Palins husband, Tim.
Palins father, Chuck Heath, says he and his wife were caribou hunting when they were told to come home and tune into their local radio station to hear exciting news, but said he did not know if his daughter was the choice for John McCains vice president.
The river was swollen, so we almost didnt get back, Palins mother, Sally Heath, told CBS News.
The two said they said the call was a wonderful surprise. I am shocked! said Mrs. Heath.
