No hints yet from holiday perennials WRCH and WMAS, but the first item in the WMAS website's slide show is about the station's Christmas tree, which I assume is some sort of do-gooder promotion.
WRCH doesn't usually flip until Thanksgiving Day. Usually at 3PM. Once at Noon. And once several year back they flipped the week of Thanksgiving because Thanksgiving was late that year like it is this year.
WMAS does a contest at Christmas time where listeners can get their prize from underneath their "94 Foot" Christmas tree.
