Open country is like a big field where you can see for miles and miles. Just like when you go outside and look around, you can see lots of things like trees, houses, and cars. But in open country, there aren't many things around to block your view. You might see some mountains or hills far away, but mostly it's just flat land with lots of grass or crops growing.
People like to go to open country to enjoy the space and fresh air. They might bring things like tents or campers to stay overnight and explore the area. Open country is also important for animals because they need space to live and move around. So, it's important that we take care of open country by not littering or harming the animals that live there.
