Well bear spray is not legal, so DONT CARRY IT! Wink wink, nudge nudge!
Secondly, just stay alert. Bears honestly dont want anything to do with us for the most part. As long as you dont stumble on one up close, or get between a sow and cubs, you are normally in no danger.
Tracking and gutting deer is when you may run into problems. Just stay alert, and get it done quickly. It helps to have a buddy watch, while you gut. Dont hang around the gut pile, and be aware if you track your deer well after the shot. I lost most of a large doe two years ago to a bear up in Montague. They also cover it with dirt and sticks and stuff, so if you find your downed deer like that, KEEP YOUR EYES WIDE OPEN! The bear may be lurking nearby waiting to eat again.
Other than that, just know how to react in different situations. Sometimes you need to be dominant and scare the bear off, other times you are the one that needs to slowly back out of the area. Never run, never scream, or get upset, just stay calm and let the bear know you are a person, more than likely the bear will run away.
Dont let bears ruin your hunt, theres not all that much to worry about.
