Thanks 2r,
good to hear from another horse packer.
I switched to soft-sided nylon panniers from the heavy hard side stuff years ago and never looked back. Hard sides were nice to sit on and to keep from breaking stuff, but just too heavy. My nylons come in about 12 pounds total. I get an apple box at the produce department stuff them in for stiffness. They're good for about two trips and also keep the siedes up and open so you can get gear in and out easily.
I hardly pack any feed until late October/November, then only if I'm on a 3 day or more hunt. I trained my horses on a picket stake and put one out all night every night, (close enough to camp I could hear if there was a tangle and a scuffle) giving the other snack time during slow part of day. They lose weight for sure, but still have energy to hunt and I don't have to mess with feed.
