I don't know where Joyce got her info....
Calls to these offices are taken immediately; faxes, E-mails, and letters will not only arrive too late, but are often left to last for review and are merely glanced at.
....but when I was in college and worked a summer as a congressional intern,
every letter was read (not glanced at

), and got a reply.
I am actually gonna do both (call and mail a letter)...but I kind of wonder where she got her information about how these things are handled.
