Thanks for the replies.  I am in the middle of the flight right now, flying outbound on the CRL 093 radial heading for COHOW.   I am dead on the radial according to my HSI.  This is the maddening part---I just got instruction from ATC to turn left to heading 065!!!!   Checking the GPS (which I hate to do when I am trying to fly without using it)  I am indeed several miles to the right of the flight plan.   Why would this happen when I am following the radial dead-on?   Why would the Navlog have 093 as the correct radial to be on when going from CRL to COHOW if that is not correct?   GRRRRR!!!
