Recently, we went on one of our most unforgettable trips. The location? The Eastern Sierra (内华达山脉东侧). Flying there took a long time, but it’s worth it. The Eastern Sierra i s huge. There are many places to explore. We visited the Museum of Western Film History. There are lots of interesting exhibits from movies like Iron Man. If you are looking for a real adventure, I recommend a trip to the Eastern Sierra.Kayak(独木舟)frightLance Borden, TexasLast summer, I went camping in Indiana with my family.
