OK, the time has come.  I have been scheduled for my polygraph for a local LE agency.  I have been reading this site and studying polygraph procedure, control questions, relevent questions, countermeasures and the works.  I am going to go into the test confident and ready to do my thing.  I will employ countermeasures and defeat the "test" and get my dream job.  I will post the experience here pass or fail.  If anyone has any last minute advice for me, please post it here.  George, thanks for all the information and advise; I hope it works.
