as a fellow jersey boy the only thing i will highly recommend is WORK ON THE CARDIO ! then when you feel like you are more than ready to run a marathon, consider yourself one quarter of the way ready. after two trips to colo., one at 8000ft and one at 10000ft, all i can say is holy crap the air is thin! that being said, it will be a trip that will create an addiction that may consume your hunting world. my wife also sent me for my 40th b-day and my 43rd, one mulie and one elk. got the mulie saw some elk. good luck with the trip.
