The 'henge' effect offers a rare and visually striking experience for residents and visitors in cities like Chicago and Denver. However, it also poses potential risks, particularly for drivers on east-west streets during sunrise and sunset. The intense glare from the sun can reduce visibility, increasing the likelihood of traffic accidents. Pedestrians and photographers seeking to capture the phenomenon are also advised to exercise caution, as stepping into streets for the perfect shot can be dangerous. The event serves as a reminder of the need for safety awareness during such celestial occurrences.
