Just quickly surfing some Fresno websites:
KAIL-53: Not listed, which is too bad since they will shut off Ch. 53 for good and move to Ch. 7.1 (my53) and 7.2 (RTN and Giants games)
KSEE-24: 7 a.m. Friday
KFSN-30: Noon Friday
KMPH-26: 9:02 a.m. Friday
KGPE-47: Midnight Friday, if I'm reading the countdown clock right
KFRE-59: Also 9:02 a.m. Friday
KFTV-21: Also Midnight Friday
KVPT-18: Flash-cut April 25
Of course, KSEE could draw more attention to the switchover if it moved it to 7 p.m. Friday, which would be about the middle of Game 7 of the Stanley Cup Finals.
