Back in the early days, when I was short on horses, tack and trailers to transport. We used to pack the horses and hike in leading the horses. Once camp was set up, I could still ride the horses around the area of the base camp.
As the years progressed and I got more horses for my daughter to ride. I started putting most of the gear on the horses my daughters where riding, The girls were lighter and not as prone to over load the horses as adding camping gear to my horse.
Now days my daughters have grow up and left home. So I have horses that need the exercise. So I take them all even if they only carry a light load. At least they are getting out and covering ground.
Hunting season in Utah often means any grass for grazing is long gone by that time of year. So I have to pack in feed. Since hunting camp is often setup and left for extended period. we can pack in camp 1st trip and make a return trip to pack in hay pellets for the horses. October camp outs at high elevation sites often see single digit night temps. Requiring heavier sleeping bags and tents that can hold up under the weight of heavy snow. So I definitely haul in more than any camp out duing the summer months,
Carrying feed in to camp using a regular western saddle with panier thrown over. The horse can still be rode each day even after being used as a pack horse for the trip in
Just as I wear different cloths for each season, Packing needs change to suite the different seasons, weather or purpose of the camp out. There will always be a need for light weight camp out. and it's great to see equipment that is now available to make a night in the back country more comfortable.
