Several years ago, I was driving a 1995 Ford Probe with a Delco factory radio... all of which require absurdly high signal levels in order to activate seek. (This one needed close to 60 dBu, from several months of informal yet diligent observation.) In Minneapolis, an Idaho Falls signal hit my seek on 93.1... and in the southern suburb of Lakeville, 94.1 KILO-Colorado Springs (classic rock) hit my seek as I was driving west just starting to climb a 150-foot hill.
(Incidentally, when I arrived at my parents' place, we were being visited by an aunt who had just moved back to MN from Colorado Springs. She was a classic-rock fan, but not the radio geek I am... so I decided to play some mind games. "Hey Lynette... you'll never believe what I heard on KILO on the way in." She actually proceeded as if this were a normal conversation, asking me what I'd heard... until finally catching herself ten seconds later and asking me, incredulously, how I knew about KILO. ;D)
