Packer pellets! a few comments on grazing... if you haven't been there previous, do you have plenty of grass? Also, have you had some trial runs? We would usually keep one of the horses up and turn the others loose to graze. and then tie the rest, and turn the others loose. you want to make sure that if you turn one loose, its not going to take off. Hobbles can help, but a lot of horses can cover ground like crazy when hobbled. The other thing to consider... if you aren't taking someone with you just to take care of horses, grazing can take a lot time.. when hunting, pellets in a feed bag may help the time factor
