I live in Texas and with our hot summers, I always travel with water. I find the easiest way to carry and offer water is in a large cooler. I can fill it in the bed of the truck and then let the horses drink from there. I have a smaller one I can lift in and out of my trailer’s tack room. My horse has learned that the blue cooler has his water. I started this with a picky drinker and now find it easier than filling buckets. At shows, I’m going to try Lynn A’s recipe. Thanks!
