Winterizing: blow-out vs antifreeze for longer term storage?

Well,,,, I know I'm the odd one in this. But, I do both. I put the pink antifreeze through the system. Then I blow the system out. This way I do not have the pink stuff setting in the lines all winter long. But, if there is a place that the air doesn't blow out good enough there is enough antifreeze in it to protect it.
