2. Welcome to OCDO in Fayetteville.
3. My routine: Get in the vehicle, secure the seat belt, start up, and drive away. Nothing special here. I do not remove the gun from the holster. Suggestions will be: a holster jammed between the seats, or seat and console; in a holster attached to the passenger seat; a holster attached to the dash or console; laying on the seat/console/dash; have the sweet thing in the passenger seat hold it on her lap, or have her drive and you hold it on your lap. If you simply lay it on a surface it stands a chance of becoming a missile during an accident or other unplanned event.
