Jobs for old cobol programmer

Hi all

I originally got my start into programming back in '74 at Corp.
Allstate as an IBM 360 assembler programmer.  Went to Corp Motorola
after a couple of years where started programming in cobol and after a
couple of years moved on to other companies coding cobol and was the
manager of an IMS/DBDC department.  I still code cobol on an old Wang
Operating System running in a VM environment but since about 92 have
coded in Topspeed, Python, Ruby some VB ,Access.  Still coding cobol
but have lost skills in jcl etc.

Any advice on looking for jobs to get back in the mainframe
environment.
