I'd check them regulations again. If it's an imposed limit by yourself not wanting to look safe while camping or a family member or fellow camper. Ignore their wishes. Better safe than sorry and if you are asking the question, then you'll feel pretty sorry of you don't properly prepare for bear defense. My wife told me the same thing once. I packed it anyway and sitting around the fire at night and the sound of bears all around wanting our food, the wife was glad imignored her.
That bear spray is awesome stuff. The sound it makes spraying will scare them off 90% of the time. And if they are up wind, all it's going to do is blind you and season their next meal.
