    Last weekend, I went hike with some friends. Setting off early in the morning, we gathered at the gate of a park in ours city. Then we headed for our destination. We have planned to climb a hill near the park. On the way, we talked, laughed or sang happily. It took us three hour to reach the top. The wonderfully view from the top made all the efforts worthwhile. We had a nice rest and picnic, sharing that we carried in our bags each other. At about four in the afternoon, we began our back trip. It was so a nice experience to get close to the nature and enjoy fresh air that we had a great day.
