writing what you don't know

They say to write about what you know. Just as important is not to write about what you are completely ignorant of. Do some research or look like a total idiot. This was triggered by a description of rabbit hunting in a story not on this site. The protagonist was hunting rabbits over bait from a blind with a shotgun. When a rabbit came in sight he carefully waited to take a clean shot when the rabbit was fully enguaged with the carrot. If this doesn't have you rolling on the floor laughing you have never been a hunter and know nothing of rabbits.
