Critter, you are the man!! What a fantastic hunt that will be! I too have dreamed of a griz hunt since I was a young kid. Unlike Hunter25 thinks, the time (ten months) will FLY by. I booked my African hunt over a year in advance and time went by quickly. I spent a lot of time working up my loads, getting my gear ready and dreaming. I think the anticipation is a huge part of the hunt. I wouldn't miss that for anything. If you had taken the first hunt, you would have cheated yourself out of ten months of dreaming and planning.
I've only seen one grizzly in real life and it was plenty scary. I had killed a moose the day before and as we neared the area, we came on this younger (only about 7 feet) bear sniffing around. I can tell you that all my partners had their rifles at the ready. I wasn't carrying because I had filled my tag.
Glad to see you've done your homework on a good taxidermist. It's worth getting the best on an animal like that. Too bad you're going north so far east of me. I'd invite you to spend the night with me, either going up or coming back down. I live just off I-5, right on the Canadian border, and you'd be more than welcome to stop by either way.
As far as your meat and hide, you might think about building a small wooden cooler lined with Styrofoam. I have one and it will keep meat cool for a full week. If you're interested, I'll send pictures and tell you how we did it.
Congratulations on getting to go and I sure hope you keep us all in the loop. Take tons of pictures.
