Hey Ko...You will be sitting over a bait pile waiting for Mr. Blackie to walk on out..It is very thick up there so they will surprise you. You will probably be in a stand.Just sit still and things will happen. Judging the size of bears is the most difficult thing. The guide should help you with this. If a drum is used for the bait and the bear is as big or bigger, SHOOT! Most bears taken by my friends up in Maine average 200-250lbs. A head net and a roll of duct tape(used to tape pant cuffs close) should help control the bugs. Aim just behind the shoulder and squeeze.....

Good luck...I' m in Somerset so let me know how you make out when you get back.
