RE: caribou - Tuttlik - 20 days here I come !
Good luck BD....I envy you...I've done 8 caribou trips and I love hunting those beautiful critters...Love EATING them, too...Wish I could afford to go every year...I hunted with Jack Hume last year and am booked to hunt with him again in 2008...
I've never hunted with Tuttilick, but I've heard lots of good stuff about them on the forums and never heard anything negative..
Enjoy yourself, hunt safe, and be sure to report in when you get back......
