No real surprises. Normal for NIC to do a 13 in December.
10 rating for 97.1 between FM and streaming. A slight bump for WOMC due to some Christmas.
Alt 98.7 slipping a little over an abnormally high 4.0
WFDF is closing in on WGPR!

WRCJ had a pretty good bump, they even beat WJR (both probably mostly the 65+ demo). Is this a Holiday music bump?
