I'm a teacher, so I have summers off and am literally in OC every weekend, and a lot of the week to surf. I have never had doors on my jeep, and my board has been affixed in very noticeable and somewhat sketchy ways involving shoe laces and the like. I have never once been hassled about no doors. I stuck one of those tiny mirrors that you put onto rear view mirrors to see your blind spot right under the vent of the jeep. It is a circular mirror, maybe 3/4" in diameter. My plan is to reference that as being my rear view mirror if I ever catch shit for no mirrors..
