i've never had to deal with bear, but i DO HAVE A HEALTHY RESPECT FOR THEM! not nesecarily afraid of them mind you, but i f i saw one, i would move along quietly and leave it alone. for me, i would be invading THEIR teratory, so I AM THE INTRUDER. i like a lof of the advice people have given about how to scare them off. they are for the most part quite shy creatures form what info i have. but i know under certain circumstanses, they can be agressive. if you are unfortunate enough to be in contact with an agressive bear, YOU WILL LOOSE! unles you have a big enough gun. your 30-30- should do the trick unless it is absoloutly charging you. i would do all i could to deter his coming around, LOOK outside with a spot light before you or S.O. go outside after dark, and maybe one of those snmall boat air horns would also go a long way to scare one off if you stumbled across one while outside. i also dont know about the lion dung thing, if it has no idea what it belongs to, why would it be scared by it? but, if you have a zoo near by, it would be worth a shot. it would be free, and it would disolve and go away after a short time. actually, the zoo may be able to give you some other helpful suggestions about how to deter the bear. it sounds like you are going about this in the right way, not just going out and shooting it to get rid of it. just be careful, and if you EVER SEE A CUB, STAY INSIDE AND CALL THE ATHORITIES! if you go outside when there is a cub, there will be trouble!
