I am a cow-horse, and I camp once a week for three months in the summer, for one day and one night at a time. The only food I brought was canned food, and the most important item was a solar high-frequency radio... In a natural environment far away from the city, I relearned to observe the changes in the four seasons and listen to the chirping of insects and birds. From the initial anxiety, I gradually became able to calm down and enjoy the time alone.
