One dozen arrows on any travel hunt doesn't make sense to me. You may be good out to 45 yards but open terrain and a constant wind could prove a difficult situation. The animals will always be moving and their large size often makes yardage guessing harder. I would bring a couple dozen arrows and a range finder in addition to a good camo rain suit and rubber boots. Good luck it sounds like you are in for a fun time. I hope you get on some animals.
