Back to the years when I attended undergraduate in Beijing, the whole city has been surrounded by hazardous smog. The air pollution level of our capital city was very high. I could even count the blue sky days on my fingers. People had to wear hygiene mask doing outdoor activities. I chose to stay indoor– reading, watching videos or shopping. I remember there was news at that time: a foreigner died in hospital because he ran 10 km outdoor every day in Beijing without wearing a mask. What kills him is the atrocious smog high in PM 2.5.
Moving to the States changes my lifestyle. I gradually fall in love with nature. The US benefits from an abundance of natural resources such as forest, oil, fresh water, mineral, coal, gas and fertile soil. Although our country counts 12% of world resources, when the big cake is divided by 1.3 billion each person gets a tiny portion.
People here usually go hiking, surfing, biking and sunbathing during public holidays. Personally, I love visiting national parks. We already went several famous national parks in the States, such as Yosemite, Grand Canyon, Zion, Antelope Valley, etc. There are two famous parks near where we currently live: one is Great Falls Park, and another is Shenandoah National Park. This summer, our whole family went to Shenandoah National Park together. There are many caves in that area due to the softest rock type from blue mountain ridges. Not far from Shenandoah, there is a second-largest cavern in the US called Luray Cavern. It is a must-see place for everyone visits Virginia.
Luray Cavern was discovered by five local men in 1878 and privately owned by the county now. Guangxi Guilin also has the similar or even better caverns than Luray. But I have never been to those caverns so far in my country. Most of the formations of the cavern are iron, calcium, and magnesium. In Luray, one unique thing here is that there is a large room to perform weddings.How romantic! (Found a picture in Google)
My father is an excellent tour guide and kept telling us the knowledge behind all the fantastic views. Luray Cavern continues to grow at the rate of one cubic inch every 120 years. There are also tour guides everywhere available for us to ask questions.
