Two years before，My sister and I got a chance to take a bike trip. The journey was really hard, especial in the mountains. At first，our leg were so heavy and cold that they felt like blocks of ice. Have you ever seen snowmen to ride bicycles? That's how we looked like. Along the way, children dressing in long wool coats stopped to look us. We found it was so cold that my water bottles freezes. To climb the mountain was hard work and as we looked around, we were surprised to see beautiful lakes shining like glass in the setting sun. What a unforgettable experience!
