Section Abbreviations, most states ONLY have one section so the STATE abbreviation is used,
others like California have many sections, plus a few like "Pacific" and "maritime" or "MDC" for Maryland -DC
you need these for some arrl contests,  print them , try to memorize them  ,
if you are using logging software,  chances are you cant log incorrect abbreviations.

listed first is for states with more than one section  and some of the more obscure sections, you might not think about !

Most of these, except for California, are self evident..   EMA for east mass,  NFL for north Florida
