There are no stallions, colts or loose dogs allowed on the trail. There is no drinking on the trail but you may do that once you are back at camp. Meals are not provided and there are many places that we go where there are towns or where the towns people put on a meal for us for a small price. There are always towns near if one wants to run into one for dinner. Water is usually available but most of us bring water with us.
Many places there are hoses to get more water.
I always bring hoses with me just in case. We camp at a number of large Washington ranches as their guests and at one we have a steak BBQ that is around 6 dollars each. Some nights we have pot lucks where we all make something to take for all to enjoy. I seem to be in charge of that this year so should be interesting. Horses should be shod with pads and there have been some sad cases where they have not been.
