Listened quite a bit to Elton John's Tumbleweed Connection CD on the way south along Route 66.
We also checked out local radio stations at various points along the way, the first being 103.1 FM an oldies format station out of Pontiac, Illinois. Once near Bloomington-Normal, I was able to pick up the Whip, WWHP out of Farmer City, an Americana station.
We couldn't find the oldies format Kool Radio station at Wilmington and believe it is no longer on the air, but the classic rock station WYMG 100.5 FM continues. We also found one of those play-most anything stations called Abe FM. Usually it is Jack or some other name. I guess Abe is appropriate to Springfield for some reason.
Nearing St. Louis we picked up 88.1 FM KDHX and enjoyed the Louisiana music they play Tuesdays from 4-7 PM.
