Man, thats funny, I am getting married on the same day and am looking for the same thing. I was all set to go up to AK to hunt with a freind for moose but then the date changed from sep 29 to the 8th and that went out the window.
I have never done it but have talked to alot of people who have gone to Colorado for elk. One of the guys was from WI and he said it cost him around $1000 for the trip, they drove his truck out there. He had alot of close calles and ended up getting a nice bull, public land and no guid. A group of people I know go each year and they say they see alot of animals and seem to get a few, all on public land without a guid. I hope to get out there some year.
