Beaver Jack summed it up pretty well.The best advice I can give you is always be aware of you suroundings.Bears are sneaky and can come up on you in a hurry.If you stumble on one with cubbs your best defence would try to put some thing between you and her,something to stop the charge.Try to make your self as small let them be the dominate one.Donot Run this will trigger predetor vs prey and the may not wan' t to eat ya but play abit.Sometimes there is nothing you can do sh** happens.If you are alone and dressing you animal keep the rifle close.Don' t be so engrossed in cleaning that you don' t listen,pairs work the best (1 cleaning and ! watching).You game calls will also atract predetors so keep alert.If calling put your back agianst a tree and keep eyes,ears and nose open.I dout your guide will put you in harms way,but you never know.If one attacks your guide don' t run help him out.Clients and freinds have ran at the sight of a bear attacking the other.

One more bit of info if you are attacked by a Blackie DO NOT PLAY DEAD,fight back as hard as you can.
