Parallax error on CWA border

We are all familiar with the parallax issues that arise with the satellite data. Sometimes that error can be in a location that may confuse the forecaster if this isn't in the front of his/her mind. I posted this mainly as a suggestion that we really hit the parallax issue hard in the training for operational staff, especially since lightning location is a significant aspect of IDSS.
