I'm investigating the (presumably Southern) use of temporally
specific/non-habitual "whenever" in Missouri.  For example:  "Whenever I
was working on this last night (referring to one specific occasion) I had
some problems," "I was in the shower whenever you came over last night,"
and, more curious, perhaps, "There was a time whenever I didn't know what I
wanted to do with my life."  I have canvassed the ADS-L archive and the
American Speech indexes and haven't found any reference to this
feature.  Any input (knowledge of this feature, recommendations for
investigating it, etc.) would be greatly appreciated.
