Lightning is one of nature’s most powerful and dangerous forces. In the summer at #RockyMountain National Park in #Colorado, you can often expect afternoon thunderstorms. Visitors should monitor the weather and postpone outdoor activities when thunderstorms are in the area. Witnessing a #lightning storm may be a thrill, but it’s not worth the risk.
